Tamoxifen (tam-ox-i-fen) is a medicine that is used for the treatment of breast cancer and endometrial (en-do-me-tre-al) cancer. In breast cancer tamoxifen stops oestrogen (a female hormone) from working in the breast tissue, this is called an "anti-oestrogen effect", which reduces the stimulation of breast cancer growth from the oestrogen in the body. Sometimes tamoxifen is used alone, other times it is used along with other medicines. Tamoxifen also has a couple of other useful effects in that it lowers cholesterol and helps keep up the bone density. It is not prescribed for these effects, but it is nice to know that there are other benefits of taking tamoxifen. While tamoxifen has been undergoing trials for prevention of breast cancer, it is not currently recommended for this. The usual dose is 20 mg or 40 mg of tamoxifen per day. Tamoxifen must not be taken during pregnancy, and therefore pregnancy should be avoided while taking tamoxifen and for 2 months after finishing taking tamoxifen (as it takes a while to leave the body).

But I thought that tamoxifen can stop your period- in fact, before I went to see her I was very happy thinking it was a sign that the tamoxifen is working. I have an appointment with the gynecologist on her urging (though I'd rather not go get examined again if it's unnecessary). I was just wondering if this has happened to anyone else and if you had the same reaction from your oncologist, and what ended up being the cause.

Tamoxifen is known to cause menstrual irregularities (including amenorrhea in some cases), so just based on what you have reported, I do not understand why your oncologist would be alarmed.

I discussed this with my onc, and the reason is - tamoxifen does not stop your body from producing oestregen - but it stops the oestregen from being able to bind with cancer cells, and thus being able to feed them. You can still menstruate on Tamoxifen; I have just started again after a year with none and its heavy too, and monthly, so far anyway.
