My lump was at 7:00, so inner, lower quadrant. I never knew if that was significant since most cancers occur in the upper, outer quadrant of the breast from what I've read. It was a small mass, about 8 mm with clean margins and a negative sentinel lymph node. I had an OncotypeDX low risk of recurrence so didn't have radiation or chemo. I tried an anti-hormone drug but had an immediate strong negative reaction to it so forewent anti-home therapy. I meet with an oncologist and a "post-surgery" surgeon every 6 months and have a mammogram and ultrasound just prior to those appointments. I also have blood work done including tumor markers. Tumor markers are imperfect data points but can be early warning signs if they are consistently rising and no other explanation is found for that rise. I think that the schedule I'm on is only for the first two years after surgery and subsequent protocol might be less frequent but I don't know that for sure yet.
