There are some natural alternatives to tamoxifen. Tamoxifen can cause cancer of the uterus, liver, etc. I had a terrible vaginal dryness and irritation, (maybe you won't), some depression, loss of libido and i'm now checking out why my platelet count was low - it can be due to tamoxifen. So, i've gone to a nutritional doctor, and am taking supplements that help excrete and block estrogen (cause of breast cancer) naturally. You can go to websites on tamoxifen and also estrogen and there is something called 'estrogen dominance syndrome', which some of you may have as well. Just helping. Even though the tamoxifen has benefits, it has many drawbacks, as well, and most if not all oncologists will not recommend anything else natural because it's all not approved by teh fda yet, but there are many studies. There is also a natural dr on line named "dr.Murray'. Check him out. I didnt' want to suffer on that tamoxifen and I really hope none of you do. Good luck.
