I was on tamoxifen after chemo, 20 years ago.
I stayed on it for 7 years. Then bleeding for as long as 17 days made me tell the Dr. I wanted to quit it.
I was told earlier, that tamoxifen could cause uterine cancer. Well, I did get it in 2001. A complete hysterectomy resulted. I'm fine now.
Even though I was stage 2, with lymph nodes involved, i've survived a very long time.
Just do what is suggested but also try to make some decisions on your own. With the internet you have so much mor information than I had.
Much good luck to you.......
