Didn't get an answer as to what is estrogen receptor positive. Raloxifene shows some promise at preventing breast cancer but is not being used in place of tamoxifen for cancer treatment now. However, one of the big reasons for using tamoxifen in breast cancer patients now is to prevent breast cancer in the other breast. This means it's of less potential benefit in a woman with a double mastectomy, for instance. The question was that I had initially stopped menstruating when placed on tamoxifen and was told I would, but I recently began to menstruate again.
Endometrial biopsy is planned.
There are questions about a lapse between ending other treatment and beginning tamoxifen. Certainly as prevention for cancer in other breast, it should be useful. And just not many studies have been done one when there's a break between other treatment and starting tam. Still continuing w it. We received questions about taking tam.
