I posted this wrongly on a different section, so I thought I better repost it here. Sorry for that.
I was diagnosed with dcis in my left breast 2 months ago and had a lumpectomy done to remove 2 tumors sized 5.5cm and 2.5cm. The cancer cells were high grade. The histology report shows clear margins. But recently a mammogram performed on the same breast shows micro calsifications near the site of excision. It is about 2cm. My surgeon wants to do a reexcision or even recommended mastectomy as she fears that it might not be fat necrosis but due to my extensive dcis which is aggressive. I am not sure what to do next. If possible a mastectomy would be my last option. Can a new dcis happen so fast in the space of 2 months? Would a biopsy on the tumor be accurate? I would appreciate if anybody in the same situation can advise. Thanks a lot.
