I'm a 59 yr old woman with a history of estrogen receptive breast cancer. My Dr. Told me that after 5 and a half years, I could go off of tamoxifen. My risk of my breast cancer returning was only 2.3 percent. After 6 months of being off of it, I'm still having several hot flashes per day. I was just wondering if they will stop anytime soon. Is my body still creating estrogen after being on tamoxifen for 5 and a half years?
