Beta blockers may help fight breast cancer

Beta blockers are known to be widely used heart drugs, but they could eventually have a role in fighting breast cancer.

One study has found that women already taking them to lower blood pressure tend to be diagnosed with breast cancer at an earlier stage and have better survival odds.

A second study finds that women who took a beta blocker while undergoing chemo for breast cancer had a lower recurrence rate.

Both studies appear in the Journal of Clinical Oncology.

Beta blockers are considered safe and inexpensive and may work by lowering stress hormones that may be involved in the spread of breast cancer.
