i recently approached my oncologist to arrange a neeedle biopsy to get molecular profiles of my nsclc. He told me the lung tumors were too small to to get a worthwhile sample. I then inquired about blood biopsies and got a similar response, namely that the blood often doesn't carry enough cancer volume to return a viable profile. Anyone have advice? Should I try a blood biopsy anyway. After two years of treatment, I still don't have biomarkers.
Thanks
