Some blood pressure meds boost breast cancer risk: Study
WASHINGTON (AFP) - Postmenopausal women who take certain blood pressure medications for 10 years or more face twice the risk of developing breast cancer, US researchers said on Monday.
Women who took calcium channel blockers saw a 2.4 to 2.6-fold higher risk of breast cancer than women who did not take hypertension medication, said the research in the Journal of the American Medical Association.
The study was observational and did not get into the reasons behind the increase, but experts said the findings may have major public health implications.
"While some studies have suggested a positive association between calcium channel blocker use and breast cancer risk, this is the first study to observe that long-term current use of calcium channel blockers in particular are associated with breast cancer risk," said the study.
