hi-I was diagnosed with breast cancer in my right breast and had a bilateral simple mastectomy as a result on January 9. there was no lymph node involvement and margins showed no cancer. I am progesterone and estrogen positive with scores of 7.9 and 9.2 respectively, and I am negative for HER2 with a score of 9.2. I am being told that I need to take a hormone reducing pill to avoid recurrence. The oncologist tells me that I have a 20% chance of recurrence without this therapy. I understand now that breast cancer cells can be found in the abdomen etc, and that the risks for metastizing with breast cancer is a concern. I have also had encometrial cancer about 7 years ago, with the result being a total hysterectomy, oophorectomy, and the removal of 42 pelvic lymph nodes, none of which tested positive. I am not at ALL excited about taking this medication after reading the side effects. Is this overkill, or legitimate cautionary procedures?
