@roywalton Interesting thank you. I had Avastin with Folfiri for my stage 4 dx for appendix cancer (now NED). I also have a small area on my lungs which is monitored as part of my 4 monthly CEA blood tests and PET-CT scan. I understand from my oncologist that they prefer not to do a lung biopsy because of the risks involved in the surgery, unless it becomes necessary to take on those risks. Any thoughts?
