I recently underwent a modified mastectomy of the left breast and am undergoing chemotherapy. My lump was 2.5 cm and I could definitely feel it. My question has to do with what I am nowfeeling on my right breast. I don't feel a lump but seem to be able to trace a duct or tube in roughly the same spot as was on my left breast. Seems to go from the upper outer quadrant to above the nipple. Should I be able to feel anything like this? Or, does that fact that I can feel it indicate there is something hard inside it? It does not seem to be a lump like what I had on the left.
