What is Biomarker Testing and Why is it So Important?

Biomarker testing looks for changes in a tumor's DNA and can help identify targeted treatments that could improve your quality of life and chances to BEAT lung cancer. The best time to talk to your doctor about biomarker testing is before a biopsy is done. This will help ensure that the doctor removes enough tissue during the biopsy to do biomarker testing. It is also important to talk about additional biomarker testing if your cancer continues to grow after you have been on a targeted therapy. Talk to your doctor about biomarker testing today.
