|A new Japanese study shows that women who spend a lot of time exercising or eat a heart-healthy diet appear to reach menopause earlier, Reuters reported.
|Doing so means women have less exposure to high estrogen levels, said Dr. JoAnn E. Manson, president of the North American Menopause Society. The hormone promotes breast tumors, and that may explain why early menopause is tied to a lower risk of breast cancer.
|On the other hand, early menopause has also been linked to increased risks of heart disease and bone thinning.
Menopause usually begins between ages 41 and 55.
