I read that theory yesterday, and it makes no sense. If hormone therapy shrinks the size of tumors and the tumors then go undetected, it would seem that eliminating hormone therapy would cause the tumors to stay the same size or grow and MORE breast cancer would be detected. Or did I misread? I don't know if I read about this on FR or via drudge.
This refers to HRT (hormone replacement therapy) which women have traditionally taken during menopause to mitigate some of the discomfort factors like hot flashes. Since HRT keeps estrogen levels high, studies in 2001-2002 showed that it was a driver in breast cancer and women, with the urging of their doctors, began to drop HRT in droves. I know I won't even consider HRT, for that reason.
