I had breast cancer in my right breast 7 yrs. ago, had a lumpectomy, & had chemo. & radiation therapy for that. I couldn't follow up with Temoxaphen because of negative receptors. Cancer was found in my left breast now, so I had a bilateral mastectomy and no cancer cells were found other than in the new cancer site when pathology was done on the removed tissue and nodes. this cancer had positive estrogen receptors. The diagnosis is good and was rated as a "0". I am now taking Femara, but am hesitant due to the 1st cancer 7 yrs. ago. I am nervous about taking any estrogen therapy. What is your opinion?
