I was also given the option of a masectomy or a lumpectomy................I chose the lumpectomy. I was stage 2 and it had only moved into a few lymph nodes. However, my surgeon removed 20 of them just to be safe. I was put on hormone medicine as I was ER+. It's been 5 years now and I've been on just about all the meds. Anastrozole, Exemestane, etc.................they are ALL awful!! However, I am still here and doing well. Listen to your Dr. and do what you feel is best for you.
