It had spread to all but four of my lymph nodes. The tests revealed that the cancer cells were estrogen receptor negative. I had 6 months of Chemo and 33 Radiation treatments. My doctor explained the tamoxifen studies to date and left it up to me whether or not to take it. I'm convinced that it was probably hormones from birth control pills and primarin that activated the cancer in my body.
Tamoxifen is a hormone.
Given that the cancer cells were estrogen receptor negative, I flushed the Tamoxifen down the toilet after taking them for about two weeks. More hormones just made no sense to me. Best of luck to you. This is the first email I've written to anyone about my own cancer experience. I hope it is helpful.
