I have two tumors in right breast - one 2.5 cm on right side and a 1.5 cm DCIS in another quadrant, so multi centric. I got neoadjuvant therapy - chemo and targeted therapy. One very good surgeon is recommending a mastectomy and another very good one - a lumpectomy to see if she can get negative margins (if not then mastectomy). What should I do? I have C cup breasts. Thank you! I am 43.
