There was this article in The Guardian: Breast cancer drug tamoxifen has long-term effect, study finds.
It says: "Professor Jack Cuzick, lead author of the paper, published in the Lancet Oncology on Thursday, said: 'Tamoxifen is a well-established and effective treatment for certain breast cancers, but we now have evidence of its very long-term preventive benefits. The preventive effect of tamoxifen is highly significant with a reduction in breast cancer rates of around a third,' ..."
That result is highly suspect, because it also says:
"The reduced incidence of breast cancer with tamoxifen did not translate into a reduction in breast cancer specific deaths (31 tamoxifen versus 26 placebo) the researchers found. In addition, five women receiving tamoxifen died from endometrial cancer compared to none in the placebo group."
So 36 people died of breast and endometrial cancer in the tamoxifen group, with only 26 breast cancer deaths in the placebo group.
The study was about 7151 ladies with a family history of breast cancer.
Think closely about taking tamoxifen. It depresses excess estrogen. If you wish to reduce your excess estrogen production without the side effects of tamoxifen, _go low carb_. You might also wish to help your liver, but dietary changes are absolutely essential.
Estrogen-dependent breast cancer is a high-carb problem to begin with. Hereditary sensitivity to high carbs leads to hereditary estrogen-dependent breast cancer ...
Anyway. Don't trust "science". Read between the lines. Especially if somebody benefits by telling world + dog that yea, take this for 20 years straight, you'll be fine!
