The Journal of the National Cancer Institute published a study that stated -- a sharp decline in the use of premenopausal hormones was followed by a drop in the rate of breast cancer.

In the recent past, large clinical trials were conducted as part of the Women's Health Initiative that raised concerns about the health risks from hormonal therapies to manage menopausal symptoms. This report led many to stop using the drugs.


Since those reports that were published in 2002, the sharp decline in hormonal drugs has also seen a decline in breast cancer cases. They are not sure if this is the only reason that breast cancer rates have dropped.

The researchers however think the results of the trial provide additional evidence that recent declines in breast cancer incidence may be due in part to a decline in the use of postmenopausal hormones.
