Thank you. I was diagnosed with stage 1 breast cancer in 2005. I had a lumpectomy, followed by radiation. Lymph nodes were clear. I took Arimidex for five years and completed the course in 2010. I recently met with my internist, who said that recent test results show that the protocol for Arimidex is now 10 years instead, given longer term studies. Do I need to start Arimidex again or is the previous treatment considered to be adequate, given my circumstances? My annual mammograms have been normal. My e-mail address is YYYY@YYYY .
