I had a partial mastectomy (lumpectomy) in March 2009 for Stage one invasive ductal carcinoma, no lymph node involvement and clear margins, pea sized tumor. I am refusing both radiation and tamoxifen because of serious side effects. I am 58 years old. I'd like to know who else has done this and has anyone had recurrence. Roseann

tamoxifen and radiation can have miserable side effects; however recent clinical trials offer hope of eliminating the need chemotherapy and surgery. Immunotherapy is a new treatment with clinical trials underway. The treatment is suppose to enable the immune system to locate and attack cancer cells specifically. The research is being funded primarily by a publicly traded company called Mentor Capital, which has a 20% stake in the company.
