Imaging is crucial for cancer patients and survivor. It gives the Oncologist a blue print on what treatment the patient should get and what stage the patient is at. Also, risk and the benefits. I’ve had 13 scans during my treatment. But I had to do it, that’s how they found my cancer, blood clots, cyst in my kidney, and if my chemo treatment was working. Which it was. If I didn’t get those scans I would’ve been dead. My friend had cancer also. She’s had over 50 CAT scans, MRIs, Pet scans. Shes been alive for 8 years now. Never been diagnosed. I agree the less radiation the better, avoid them if you need too. But it’s also saved lives.
Don't be sad. Make up for it by taking high doses of vitamin D (around 10,000 IU a day) and eat more fruit and vegetables ... raw if you can. If you lessen the risk, then it will balance out your CT scans. I hope that makes sense. Now go buy vitamin D3!
From current studies, Dental scans carry a very very small risk (around 50% of your daily radiation exposure depending on country): www.ifish.net/gallery/data/500/banana-chart-watermark.jpg
What questions should people ask before they get a Pet scan or CT? Should they ask what chemical will be used in them as a tracer and how much, so they can find out about the dangers beforehand? I guess they should also as the actual amount of radiation the accumulated full body PET or CT would give on the average person at one time too right? Or maybe they should also ask for written specs of the PET scan or CT? Any other questions? I heard recently that low level radiation is even more dangerous than high. I also found out that some scans are both PET & CT combined. In those cases would they use both at once on all patients, or can they just use one or the other separately? How would a patient know if they used both when they were told they would just use one?
They should ask for the radiation dose in millisievert (mSv), if there is an alternative procedure with less or no radiation and of course if the benefits outweigh the risk. In short: Dose Alternative Justification
Getting a diagnoses is sometimes the worst thing you can do because they then give you drugs and chemo etc. It would be better to not take the test and change your diet and get exercise and reduce stress in your life. The body is a wonderful healer of itself if you give it the right resources.
Hi Dr Greg, Im a subscriber and I would like to know if there is a way to reverse RADIATION damage to DNA caused by medical imaging test like CAT scans and Xrays, I would appriciate if you could post a video regarding this question.
Check out the channel! "Fruit that repair dna damage" it goes without saying because a lot of medical research hasn't been done on that specifically but be sure to eat lot of fruit and dark leafy veggies especially! Kiwi eating can raise dna repair by a lot. Strawberries, lemon(uncooked) as well.
There certainly is. X-rays induce their damage by creating free radicals, or reactive oxygen species, in the body. You can scavenge these rascals by consuming antioxidant-rich foods or supplements either before or post examination. There's plenty of studies demonstrating the effectiveness of such a technique.
For many years I have suffered from myelodysplastic syndrome (MDS), refractory anemia. Only my red blood cells were involved. Eighteen months ago I had two cat scans and a coronary catheterization done. Shortly after my platelets went below the normal range. Now I have to undergo chemo with Vidaza. I am pretty sure all the X-rays catalysed the worsening of my condition
If you are studying medicine please remember to look up literature on studies done on how food and nutrients affect cancer cell apoptosis etc. Always keep an open mind if you want to be the best in your field.
"Without the source of funding for the study cited, we can only assume it was funded by an entity that is in a direct conflict of interest and has much to be gained by dismissing low dose radiation as a significant cancer risk."
I had chest abdomen and pelvis today, and I got hit by a car a few months ago and got a head scan back then too. Im not even 20 years old yet. Nothing we can do now just dont run out and get a scan unless you actually need it.
in a car crash you need it no matter what the risk of having a brain hemorage or internal bleeding is way way higher than the insignificant risk of getting cancer from those ct scans.
It’s scary.. but each time they convince you that it’s worth the risk to know what’s going on in there. So you really don’t have much ground to make the decision yourself.
@@isabellamarinilli3990 I got one but I'm old. My young dautyher got one when she was young and it has broke my heart. Her head was bleeding we were panicking and Dr. Recommended it. Truth is there wasn't a need for it for the type of injury. The only reason the got her in there was to give the machine some usage time. Having techs sit around is expensive so giving people a little bit a cancer is not a big deal if you can keep people in the health care system busy.
@@LoneGRoEnt sickening. Not to mention they try and cover it up. After I got my head CT and developed radiation sickness I went to all these doctors trying to see if the damage from the radiation can be reversed. Get this, they denied my symptoms and said the radiation is small and safe and do not cause any side effects. Then they tried to commit me to a mental hospital for being “delusional” when I am a completely sane person who wants physical help from damage the doctors created. Luckily I was able to find an honest doctor who agreed I had radiation sickness and took me seriously. I am now getting treated for the burns, rashes, vision loss, bloody nose, bloody ears, dried tongue, lumps in throat, veins that burn and spread all over my body, collapsing lungs, internal stomach bleeding, colon problems, and hollow cracking bones. All symptoms I did not have before I award perfectly healthy. All I had was intense migraines. The reason why I went to the ER was because my migraines got so bad I felt like fainting one day and wanted to make sure it was really migraines and not something else. But other than that I was completely healthy. And the doctors at the hospital who performed my CT deny these symptoms because they don’t want to admit they gave me radiation sickness because they are afraid of getting sued. I am trying to sue them now but it’s a lot harder than I thought. You see after my head CT my chest was in extreme pain so I went back to the ER. They told me it was just anxiety and to go home but I demanded an X-ray. The X-ray came back normal but I did not trust that hospital anymore so I went somewhere else to get it done. And guess what they noticed one of my lungs were collapsing. And I have always have had healthy lungs, like I said I was completely healthy. I used to run marathons and did gymnastics and never had any chest pain ever! I went home and what do you know collapsing lungs are a symptom of radiation sickness. These people wanted to let me die to cover up their wrong doings. If your baby did not have any immediate symptoms after the head CT then your baby should be fine because I heard that pediatric CTs are lower in radiation dose. I hope. My problem is that they gave me the normal radiation dose of an adult. Which makes sense because I am 19 however I am a very tiny young woman. I am only 5 feet and very skinny. The doctor I am seeing now told me they should have set the machine to a lower dose because I am small. That and I have always been sensitive to medicine and other stuff. But yeah I was able to see how evil healthcare in America can be. Not to mention having to wait for like 7 hours in the ER. I saw so many patients in excruciating pain in the ER waiting room for emergencies and they made them wait 7 hours or more. Then you see these doctors on break on their phones it’s honestly sickening. As someone who was always healthy before and didn’t see the doctor as much I never realized how bad the healthcare is until now. I went to the ER for migraines and came out with all these other symptoms. Sad because growing up in America I was always told it’s one of the best countries and that doctors were heroes who save and help people. Yeah I don’t see them as that anymore. Who knows maybe they have CT scans for population control or too get more money from chemo when the people who got CT scans get cancer later on. Honestly at this point I wouldn’t put it pass them. Also in the WR waiting room I talked to this woman who told me very similar sickening stories of her visits to doctors it’s just unbelievable. These doctors are hurting and killing people and are getting away with it someone really needs to speak up about these things.
Radiation passes straight through you. DNA damage occurs. Too late damage is done. This happens to you everyday but with X-rays etc it’s a years worth of ‘days damage’ But you can reduce dna damage with a good immune system to clean it up as well as plant polyphenols but what you don’t want to do is overload the work to be done. And each time is another ‘spin of the wheel ‘ chance taken to get a cancer. Most times you won’t. But play enough and someone strikes it.
Shit... A couple years ago I had a car accident and at the hospital a doctor took a ton of xrays of my arm. I seriously lost count! Should I be worried? x_x
Depends on the scan (abdominal scan carry greates risk Vs chest scan). In Denmark, we generally don't use any scans on pregnant women if avoidable (as I'm sure in most countries). But even if you had a CT scan, the threshold for severe defects are around 100 mSV. The "worst" single scan in term of foeatus-radiation is the pelvic CT (25 mSV). Abortion is, in Denmark, never considered until you go over 100 mSV, and even then, is rarely offered This knowledge is based on international studies, and should therefore apply to your country as well.
I have a brain tumour caused by 2 "high contrast" CT scans (put a hole in my skull in the kitchen making coffee) which is proven as the type of tumour I have is well known and can only be caused by radiation and is normally female predominate, it just sucks to be the 1 in a hundred or thousand or ten thousand or million so don't do it no matter what the risk.
@@apothos666 As far as I'm aware I've received the equivalent of between 2400 to 3600 normal X-rays to the head (you should never have more than 4 X-rays to any part of your body). Within four years I grew a Tennis ball sized brain tumor mid brain. At it's growth rate I was expected to only live three months. 13 years this October from the event I know more about cancer than anyone wants to know. I had to save myself as when the tumor was discovered I was declared terminal which is a withdrawal of conventional treatment because if I die during treatment that's a black mark against any treating doctor. I lived because I treated myself with a combination of Methionine restriction and carb restriction. Dietary Veganism saved my life and proved to me that humans are herbivores not carnivores.
I love most of your videos, but here you are taking some bad science into account. They are extrapolating the risks from atomic bomb survivors and or not taking into account previous medical conditions. Takeaway probably a CT scan wont cause cancer on you but don't get them often. There seems to be a threshold according to most studies and some even show an hormetic response. Low doses prevent cancer instead of causing it like higher doses. Still a whole body CT scan is around 15msv so you need about 6 to get above the threshold in your lifetime so if posible avoid them but don't fear them if you need them.
The data is not full proof , yeah its possible but there's too many confounding variables to account for. Hormesis is a plausible hypothesis but the results are stochastic. Another model shows that at low doses, Ionizing radiation could have a steeper gradient i.e. could potentially be more harmful. Most people extrapolate from the LNT model. The problem is, a lot of experts play nonchalant about the effects of a Ct or X-Ray scan when in reality its extremely dangerous. These high energy waves hit electrons at an sub atomic level, changing the very nature of the molecule. they literally bust the Double strand of your DNA. the low dose X ray on average may cause 4 Dsbs per cell , seemingly small but in the grand scheme of billions of cells you can imagine how huge the damage is. A single X ray could be about 0.2 msv and people will argue that in a year we naturally exposed to about 2.4 msv but theres a huge difference , that 2.4 msv is spread out over a year while the 0.2 msv is blasted in a fraction of a second overwhelming our DNA repair mechanisms hence leading to dna mutations or epigenetic changes.It takes a single unlucky mutation to sprout a tumor and change the course of your life , is the risk worthed ? We are not totally blind , they are other imaging modalities we can opt for if need be. There also other damages too from Ionizing Radiation.
Im 63 and have had 3 stress and thallium heart scans since 1994 and so far so good but now Im a little concerned because I may need to have another stress test in the future since I am a heart patient.
@@rudfil Crazy timing for this comment: My kid just had two x-rays in the past week for a delicate fracture which might need surgery and all these x-rays always get me worried. This kid has had ct's and the whole nine. The CT could have been avoided but I didn't know any better. I also had a CT that could have been avoided. No need to cook our heads and blow tooth fillings up for nothing.
1400 cigarettes is 70 packs. That’s approximately two months and a week worth of smoking a pack a day. We base concern regarding lung Cancer risk on smoking a pack a day for 10 years. I’m not justifying unnecessary Radiology studies at all. I’m against them. just trying to put it into context so that we are not overly fear mongering.
You do that. But don't come crying to your GP when its too late. I agree diet, training and lifestyle is the one most important thing you can do. You know that, the doctor know that but no matter how careful you are, you can still get sick. Im studying medicine and have seen super healthy people still get sick. Its just being ignorant thinking doctors are stupid and the only thing you need to do is eat your salad.
I am 19 and have to have a CT Scan because I fell and have fluid gushing out of my nose and ears.... Should I not get a CT scan? (this is a serious question!!!!! Not sarcasm!!!) Should I refuse a CT Scan even though I might have a severe head injury???
Huh, kellyat31, your channel appears to have no activity but this one very critical yet unfounded comment. Odd. Gonna assume you are an industry shill, and ignore it.
Wouldn't the dangers to seniors who are fragile and who have weak DNA to start with be even more dangerous than it would be in children? When you show a picture saying size of cohort, I'm not sure what that means or what the chart shows if it means the number of people in a group. Does this mean that Canada irradiates far more people than any other country?
Sorry luceymajor, but you need to rethink your bad advice. 10,000 IUs of Vitamin D can be harmful. That is way too high. The only reason a person should take such a high dose is if they are severely deficient in Vitamin D. Otherwise, 1000-2000 IUs is fine, with 5000 IUs being the limit.
The cancer will kill you before the drugs do. When you have cancer no diet will reverse that. There are differences among cancers but if you know chemo/surgery will give you an additional 5 years. Will you not take it? Regarding diabetes, hypertension and atherosclerosis I agree is best treated/prevented by lifestyle. Doctors try tell their patients that, but compliance is incredible low. Should you not give drugs when you see your patient cant do the changes them self?
Seems like you're pretty diluded and very misinformed. Stop hurting people by spreading misinformation. If you do that rather don't comment. There's plenty of evidence that people with cancer that change their lifestyle live much longer compared to if they didn't. You are part of the problem. You are part of the people who keep people from changing their lifestyle because they have no hope and think they can't do anything although that's very wrong. Think of what you do before you write..
maybe in my entire life. A doctor did give me one cuz i had a bad headache once. what a waste that was. My headache went away an hour after the ct scan.

Don't be sad. Make up for it by taking high doses of vitamin D (around 10,000 IU a day) and eat more fruit and vegetables ... raw if you can. If you lessen the risk, then it will balance out your CT scans. I hope that makes sense. Now go buy vitamin D3!
@@luceymajor vitamin D to offset the vitamin X!
Smart move! I am currently curing my own "incurable" fibromyalgia.
Is this the same for dental x-rays?
From current studies, Dental scans carry a very very small risk (around 50% of your daily radiation exposure depending on country): www.ifish.net/gallery/data/500/banana-chart-watermark.jpg
What questions should people ask before they get a Pet scan or CT?
Should they ask what chemical will be used in them as a tracer and how much, so they can find out about the dangers beforehand?
I guess they should also as the actual amount of radiation the accumulated full body PET or CT would give on the average person at one time too right?
Or maybe they should also ask for written specs of the PET scan or CT?
Any other questions?
I heard recently that low level radiation is even more dangerous than high. I also found out that some scans are both PET & CT combined. In those cases would they use both at once on all patients, or can they just use one or the other separately? How would a patient know if they used both when they were told they would just use one?
They should ask for the radiation dose in millisievert (mSv), if there is an alternative procedure with less or no radiation and of course if the benefits outweigh the risk.
In short:
Dose
Alternative

Getting a diagnoses is sometimes the worst thing you can do because they then give you drugs and chemo etc. It would be better to not take the test and change your diet and get exercise and reduce stress in your life. The body is a wonderful healer of itself if you give it the right resources.
are they ways to heal after a CT scan?
yes lemon juice before CT scan and spirulina after; and NAD+ i think
@@dogecrypto8126 Where did you get that info from? Thanks.
Hi Dr Greg, Im a subscriber and I would like to know if there is a way to reverse RADIATION damage to DNA caused by medical imaging test like CAT scans and Xrays, I would appriciate if you could post a video regarding this question.
Check out the channel! "Fruit that repair dna damage" it goes without saying because a lot of medical research hasn't been done on that specifically but be sure to eat lot of fruit and dark leafy veggies especially! Kiwi eating can raise dna repair by a lot. Strawberries, lemon(uncooked) as well.
There certainly is. X-rays induce their damage by creating free radicals, or reactive oxygen species, in the body. You can scavenge these rascals by consuming antioxidant-rich foods or supplements either before or post examination. There's plenty of studies demonstrating the effectiveness of such a technique.
Lemons are good
Just drink natural lemon juice
For many years I have suffered from myelodysplastic syndrome (MDS), refractory anemia. Only my red blood cells were involved. Eighteen months ago I had two cat scans and a coronary catheterization done. Shortly after my platelets went below the normal range. Now I have to undergo chemo with Vidaza. I am pretty sure all the X-rays catalysed the worsening of my condition
omg thank u for this! so glad I found this vid. and YES u r so rite, live rite and u wont need this crap in the 1st place!
If you are studying medicine please remember to look up literature on studies done on how food and nutrients affect cancer cell apoptosis etc. Always keep an open mind if you want to be the best in your field.
How about those full body scans they do at my local mall? You know the virtual exam?
any research on dental xrays of all kinds?
How many ct scan safe & if pelvis scan how many time rotate the disc
Ok, I had a chest ct-scan....and now I am scared as fuck about the risk of getting cancer....
"Without the source of funding for the study cited, we can only assume it was funded by an entity that is in a direct conflict of interest and has much to be gained by dismissing low dose radiation as a significant cancer risk."
by the confidence of your statement, we can only assume that you have proof that CT scans DO NOT increase risk of cancer, mind sharing it?
Wentao Feng the risk is too small to be worried about
I had chest abdomen and pelvis today, and I got hit by a car a few months ago and got a head scan back then too. Im not even 20 years old yet. Nothing we can do now just dont run out and get a scan unless you actually need it.
in a car crash you need it no matter what the risk of having a brain hemorage or internal bleeding is way way higher than the insignificant risk of getting cancer from those ct scans.
It’s scary.. but each time they convince you that it’s worth the risk to know what’s going on in there. So you really don’t have much ground to make the decision yourself.
Where can the studies listed at 1:48 be viewed?
Thank you for whistle blowing!
so... results should be in by now?? 1:46
I regret getting my baby under a CT Scan. I just had one done I was in an ER and out of it. Didn't even need it... Both head CT's...
Head CTs are dangerous. I got one and my whole body was effected
@@isabellamarinilli3990 I got one but I'm old. My young dautyher got one when she was young and it has broke my heart. Her head was bleeding we were panicking and Dr. Recommended it. Truth is there wasn't a need for it for the type of injury. The only reason the got her in there was to give the machine some usage time. Having techs sit around is expensive so giving people a little bit a cancer is not a big deal if you can keep people in the health care system busy.
@@LoneGRoEnt sickening. Not to mention they try and cover it up. After I got my head CT and developed radiation sickness I went to all these doctors trying to see if the damage from the radiation can be reversed. Get this, they denied my symptoms and said the radiation is small and safe and do not cause any side effects. Then they tried to commit me to a mental hospital for being “delusional” when I am a completely sane person who wants physical help from damage the doctors created. Luckily I was able to find an honest doctor who agreed I had radiation sickness and took me seriously. I am now getting treated for the burns, rashes, vision loss, bloody nose, bloody ears, dried tongue, lumps in throat, veins that burn and spread all over my body, collapsing lungs, internal stomach bleeding, colon problems, and hollow cracking bones. All symptoms I did not have before I award perfectly healthy. All I had was intense migraines. The reason why I went to the ER was because my migraines got so bad I felt like fainting one day and wanted to make sure it was really migraines and not something else. But other than that I was completely healthy. And the doctors at the hospital who performed my CT deny these symptoms because they don’t want to admit they gave me radiation sickness because they are afraid of getting sued. I am trying to sue them now but it’s a lot harder than I thought. You see after my head CT my chest was in extreme pain so I went back to the ER. They told me it was just anxiety and to go home but I demanded an X-ray. The X-ray came back normal but I did not trust that hospital anymore so I went somewhere else to get it done. And guess what they noticed one of my lungs were collapsing. And I have always have had healthy lungs, like I said I was completely healthy. I used to run marathons and did gymnastics and never had any chest pain ever! I went home and what do you know collapsing lungs are a symptom of radiation sickness. These people wanted to let me die to cover up their wrong doings.
If your baby did not have any immediate symptoms after the head CT then your baby should be fine because I heard that pediatric CTs are lower in radiation dose. I hope. My problem is that they gave me the normal radiation dose of an adult. Which makes sense because I am 19 however I am a very tiny young woman. I am only 5 feet and very skinny. The doctor I am seeing now told me they should have set the machine to a lower dose because I am small. That and I have always been sensitive to medicine and other stuff. But yeah I was able to see how evil healthcare in America can be. Not to mention having to wait for like 7 hours in the ER. I saw so many patients in excruciating pain in the ER waiting room for emergencies and they made them wait 7 hours or more. Then you see these doctors on break on their phones it’s honestly sickening. As someone who was always healthy before and didn’t see the doctor as much I never realized how bad the healthcare is until now. I went to the ER for migraines and came out with all these other symptoms. Sad because growing up in America I was always told it’s one of the best countries and that doctors were heroes who save and help people. Yeah I don’t see them as that anymore. Who knows maybe they have CT scans for population control or too get more money from chemo when the people who got CT scans get cancer later on. Honestly at this point I wouldn’t put it pass them. Also in the WR waiting room I talked to this woman who told me very similar sickening stories of her visits to doctors it’s just unbelievable. These doctors are hurting and killing people and are getting away with it someone really needs to speak up about these things.
@@LoneGRoEntHey I'm sure everything's gonna be alright for your young ones 🙏
I love your videos! Keep on :-)
Wow... This is scary... How can you fight radiation out of the body, if at all possible?
Radiation never leaves your body! It accumulates through your lifetime!
Radiation passes straight through you. DNA damage occurs. Too late damage is done. This happens to you everyday but with X-rays etc it’s a years worth of ‘days damage’ But you can reduce dna damage with a good immune system to clean it up as well as plant polyphenols
but what you don’t want to do is overload the work to be done. And each time is another ‘spin of the wheel ‘ chance taken to get a cancer. Most times you won’t. But play enough and someone strikes it.
most cat scans are done unnecessarily, as the video notes, watch the video and learn.
Vets forced me to get cat scans just because he was constipated. I also hate it that dentists force you to do that.
Sure its not good for you and all doctors know that. But is it worth refusing to take one and possible missing out on an diagnosis. I dont think so
Shit... A couple years ago I had a car accident and at the hospital a doctor took a ton of xrays of my arm. I seriously lost count! Should I be worried? x_x
Eat a lot veggies and fruit!
Worried. Weren't you worried about having a broken arm. If so, then they can fix it.
@@Hitogata x rays are way less radiation then a ct scan
Scary! My granddaughter had at least 2, maybe 3, CT scans when she was only a few months old :(
veganangel68 omg these doctors idk what to say about this medical system anymore
Now how old your granddaughter?
I have an abdominal pregnancy and I have had a CT scan I understand that the risks are low. Is this correct?
Depends on the scan (abdominal scan carry greates risk Vs chest scan). In Denmark, we generally don't use any scans on pregnant women if avoidable (as I'm sure in most countries).
But even if you had a CT scan, the threshold for severe defects are around 100 mSV. The "worst" single scan in term of foeatus-radiation is the pelvic CT (25 mSV). Abortion is, in Denmark, never considered until you go over 100 mSV, and even then, is rarely offered
This knowledge is based on international studies, and should therefore apply to your country as well.
I have a brain tumour caused by 2 "high contrast" CT scans (put a hole in my skull in the kitchen making coffee) which is proven as the type of tumour I have is well known and can only be caused by radiation and is normally female predominate, it just sucks to be the 1 in a hundred or thousand or ten thousand or million so don't do it no matter what the risk.
I think it’s much more common that they want you to believe
I'm so sorry. I had 2 head CTs done, now I'm terrified.
Do you know the doses of those two scans?
@@apothos666 As far as I'm aware I've received the equivalent of between 2400 to 3600 normal X-rays to the head (you should never have more than 4 X-rays to any part of your body). Within four years I grew a Tennis ball sized brain tumor mid brain. At it's growth rate I was expected to only live three months. 13 years this October from the event I know more about cancer than anyone wants to know. I had to save myself as when the tumor was discovered I was declared terminal which is a withdrawal of conventional treatment because if I die during treatment that's a black mark against any treating doctor. I lived because I treated myself with a combination of Methionine restriction and carb restriction. Dietary Veganism saved my life and proved to me that humans are herbivores not carnivores.
Don't be scarred, be your best self always, look learn and listen. The universe will only give you what you need when you are ready.@@apothos666
I love most of your videos, but here you are taking some bad science into account. They are extrapolating the risks from atomic bomb survivors and or not taking into account previous medical conditions. Takeaway probably a CT scan wont cause cancer on you but don't get them often. There seems to be a threshold according to most studies and some even show an hormetic response. Low doses prevent cancer instead of causing it like higher doses. Still a whole body CT scan is around 15msv so you need about 6 to get above the threshold in your lifetime so if posible avoid them but don't fear them if you need them.
Hi Omar. Interesting claim. Do you have an literature that you can cite? -Thanks
@@squirtlesquirtle94 google radiation hormesis ncbi
The data is not full proof , yeah its possible but there's too many confounding variables to account for. Hormesis is a plausible hypothesis but the results are stochastic. Another model shows that at low doses, Ionizing radiation could have a steeper gradient i.e. could potentially be more harmful. Most people extrapolate from the LNT model. The problem is, a lot of experts play nonchalant about the effects of a Ct or X-Ray scan when in reality its extremely dangerous. These high energy waves hit electrons at an sub atomic level, changing the very nature of the molecule. they literally bust the Double strand of your DNA. the low dose X ray on average may cause 4 Dsbs per cell , seemingly small but in the grand scheme of billions of cells you can imagine how huge the damage is. A single X ray could be about 0.2 msv and people will argue that in a year we naturally exposed to about 2.4 msv but theres a huge difference , that 2.4 msv is spread out over a year while the 0.2 msv is blasted in a fraction of a second overwhelming our DNA repair mechanisms hence leading to dna mutations or epigenetic changes.It takes a single unlucky mutation to sprout a tumor and change the course of your life , is the risk worthed ? We are not totally blind , they are other imaging modalities we can opt for if need be. There also other damages too from Ionizing Radiation.
Im 63 and have had 3 stress and thallium heart scans since 1994 and so far so good but now Im a little concerned because I may need to have another stress test in the future since I am a heart patient.
By stress test do you mean a nuclear stress test?
at your age it probably wont do much harm take your veggies and eat garlic before the scan.

how are you now please tell us
Who else still here ?
1400 cigarettes is 70 packs. That’s approximately two months and a week worth of smoking a pack a day. We base concern regarding lung Cancer risk on smoking a pack a day for 10 years. I’m not justifying unnecessary Radiology studies at all. I’m against them. just trying to put it into context so that we are not overly fear mongering.
It is a personal decision either to smoke or not, but in the CT Scans, it is a damage on the body induced by the MD that order them.
Thank you for sharing!
Stupendo video!,impressionante!
You do that. But don't come crying to your GP when its too late. I agree diet, training and lifestyle is the one most important thing you can do. You know that, the doctor know that but no matter how careful you are, you can still get sick. Im studying medicine and have seen super healthy people still get sick. Its just being ignorant thinking doctors are stupid and the only thing you need to do is eat your salad.

Huh, kellyat31, your channel appears to have no activity but this one very critical yet unfounded comment. Odd. Gonna assume you are an industry shill, and ignore it.
Wouldn't the dangers to seniors who are fragile and who have weak DNA to start with be even more dangerous than it would be in children? When you show a picture saying size of cohort, I'm not sure what that means or what the chart shows if it means the number of people in a group. Does this mean that Canada irradiates far more people than any other country?
great YT channel
Sorry luceymajor, but you need to rethink your bad advice. 10,000 IUs of Vitamin D can be harmful. That is way too high. The only reason a person should take such a high dose is if they are severely deficient in Vitamin D. Otherwise, 1000-2000 IUs is fine, with 5000 IUs being the limit.
@@womanintheshadow you know that your skin make 16000 when you sunbathing for an hour with 80% uncovered body?
The cancer will kill you before the drugs do. When you have cancer no diet will reverse that. There are differences among cancers but if you know chemo/surgery will give you an additional 5 years. Will you not take it? Regarding diabetes, hypertension and atherosclerosis I agree is best treated/prevented by lifestyle. Doctors try tell their patients that, but compliance is incredible low. Should you not give drugs when you see your patient cant do the changes them self?
Seems like you're pretty diluded and very misinformed. Stop hurting people by spreading misinformation. If you do that rather don't comment. There's plenty of evidence that people with cancer that change their lifestyle live much longer compared to if they didn't. You are part of the problem. You are part of the people who keep people from changing their lifestyle because they have no hope and think they can't do anything although that's very wrong. Think of what you do before you write..
