Jane sorry to hear of your diagnosis.... What kind of BC do you have? That may make your decision a little easier. For me I have Invasive Ductual Carcinoma 3cm with 1 SN positive. I had a lumpectomy to remove tumor and lymph nodes and then I had 4 rounds of AC chemo. The next step was radiation but I decided against it and now looking into double mastectomy, also need to be on hornome blocking treatment, good luck with your decision just ask as many questions the girls here are very supportive and full of information.
