Long Term Use of Blood Pressure Medicine May Increase Risk of Breast Cancer

A recent study found a link between long term use of calcium channel blockers, like Pfizer’s Norvasc, and the onset of breast cancer. JAMA reported that women who took calcium channel blocker blood pressure medicine for 10 years have a 2.5 higher risk of developing breast cancer than women who never took blood pressure medication. Research is being done to replicate the findings. In light of these findings, we expect additional information to be released from FDA, independent and industry funded sources, and other outlets, debating the risk. If the manufacturers were aware that these medications more than double the risk of developing breask cancer, and failed to warn of this risk, the right thing to do is to properly compensate the cancer victims.
