Totally understand, @ema1 - A similar thing happened in my case. Actually, in my case, the top margins were NOT clear at all! My surgeon explained that she had recognized that. However, her choice was to cut through the chest muscles. She had consulted with the Radio Oncologist and the two decided to avoid that, but YES, I did have Radiation treatment.

As it turned out, I would have needed to do radiations regardless. My radio oncologist sent my specimen to a particular lab, the reply was my type of cancer was pretty aggressive. They indicated my potential for reoccurrence was "high" without doing radiations.

Bottom line: I didn't need more surgery, and my treatments were done belly down. A bit more uncomfortable, but safer (according to my radio oncologist). Radiations done that way, largely spare the organs that could be damaged (heart and lungs).

HUGS,
