I had the WLE and SNB, clear nodes, but not clear margins. Mastectomy in 4 weeks. I had multi focal IDC.
But, my onc explained that due to my young age (41), and the aggressive type disease I should have chemo. Sometimes the cancer cells can spread despite clear pathology apparently, so it was a precaution. In fact, she said it would not affect the DCIS left in the breast after surgery, maybe just limit its growth.?
I decided to have both breasts off even though only the one was affected with cancer. I just don't trust the scans after my experience. It makes me feel better, but I've read that mostly ladies go for just the affected breast like you.
You've got to go with what's right for you. I hope you find your answers.
