Estrogen and Bone Mass

The relationships between estrogen and bone mass on the one hand and estrogen and breast cancer on the other hand have been studied extensively.

Now The New England Journal of Medicine reports a disturbing study of the relationship between bone mass and breast cancer.

They found that the greater the bone mass (less osteoporosis) in post-menopausal women, the higher the chance of breast cancer.

They conclude that it may be that estrogen, which protected the women against osteoporosis, may play a part in the increase in breast cancer.

This is more reason for women approaching menopause to carefully discuss the advantages and disadvantages of estrogen treatment with their doctors before committing to treatment.
