Previously, UKidney News reported a possible link between calcium channel blockers and the development of breast cancer. Data from the Intermountain Medical Center Heart Institute study were presented at the 2014 American Heart Association Scientific Sessions in Chicago, dispelling some of this concern:
"We found no robust data that calcium channel blocker medications increase a person's risk of breast cancer," said Jeffery L. Anderson, MD, a cardiologist and researcher at the Intermountain Medical Center Heart Institute. "Given the important role calcium channel blocker medications play in treating heart conditions, we think it's premature to discontinue their use. At this point we recommend that patients continue taking these medications to treat their hypertension."
While it is very difficult to ever prove a negative association, these data do provide some reassurance to a large number of patients using this important antihypertensive.
