I'm not the best person or even close to give unbiased advice on this. I am very biased as my mother was one of those to get breast cancer, and also congestive heart failure after being on HRT. They will not say that the HRT caused the breast cancer (though there is NO family history of it) but they did say it was probably the cause of the CHF. They do admit though that it probably did cause the breast cancer to grow at such a fast rate.
My mother has now been cancer free for 4 years, but the heart problem has almost killed her. They had to use such strong doses of chemo because her cancer would not respond to the other. (the cancer advanced extremely quick) The strong doses of chemo damaged her heart even worse. She is not eligible for a heart transplant until she is cancer free for 5 years, then she goes on a waiting list.
I will never take the HRT. I think natural remedies are the safest way to go.
Goodluck!
