Breast cancer survivors can have ongoing health challenges after they’ve beaten "The Big C." Many are on medications that block estrogen, the hormone that drives most breast cancers. These medicines also increase the risk of osteoporosis (brittle bones) and increase the risk of fractures.

Medications that block estrogen can be life savers for some breast cancer survivors. But does this approach help all breast cancer survivors?

The majority of breast cancers are fed by the hormones estrogen and progesterone. That’s why women with hormone-sensitive breast cancer are prescribed medicines to block these hormones. But a good portion of women may be skipping the therapy.

Here’s an intriguing thought. What if we could reprogram cancer so it responds to treatment? That’s exactly what breast cancer experts are exploring.

Not all women respond to a common breast cancer drug called tamoxifen . Not to worry–these women can now be identified and switched to another medication before the disease turns deadly.
