I had a double Mas. and BC has returned after a so called rogue cell in the arm pit area (all BC of left side) Radiation hasn't helped me. I had suspiciously confused technicians in '19 and '22 in Fl, then NC. they shuffled and fumbled around with starting machinery then changing position of it , I felt electric shocks leaving the Fl clinic. , then in NC the 2 techs were disagreeing in front of me once procedure started; stopping standing around me talking over me as I lay perfectly still hoping for a miracle . They said something about colors saying, "no I do the brown and the other said no I always just do yellow. And it was sort of some sort of shrug of the shoulders I guess I do not think I was positioned to look at them and they just walked away and started again. I'm burned to a crisp after a few month, have limited range of motion there and sunken missing tissue (which I guess is necrosis) If I was having a lumpectomy, I'd definitely say, PLEASE do very GOOD clear margins to help cut out more chances of rogue cells being left behind.
