Blood pressure medications may raise risk of breast cancer recurrence

(USA Today) —  Two commonly used blood pressure medications seem to have opposite effects on the chances of breast cancer recurring in women with a personal history of the disease.

Preliminary findings show that ACE inhibitors increased the risk of recurrence, which surprised even the researchers, who published their study online in the journal Breast Cancer Research and Treatment.

On the other hand, beta blockers seemed to reduce the risk, which is in keeping with prior studies on the subject.

Fortunately, when the two drugs were combined, beta blockers seemed to mitigate the increased risk of recurrence linked with ACE inhibitors.

The study reflects the increasing interest among scientists in the effect the “microenvironment” — which can include chronically used medications in addition to alcohol, tobacco and physical activity — might have on the course of a particular woman’s breast cancer.
