Some research shows that women taking blood pressure drugs have about a 250 percent greater risk of developing some types of breast cancer than other women.
Nearly one-third (32.7%) of American women have high blood pressure, according to the Centers for Disease Control and Prevention. While many individuals with high blood pressure change their diet and increase activity levels to keep blood pressure under control, others are content to rely wholly on the chemical concoction prescribed by their doctor. There are many problems with blood pressure medications though—one of which is a significant increase in the risk of breast cancer for women.
According to a recent study published in the journal Internal Medicine, women taking calcium channel blockers like nicardipine (Cardene) and amlodipine (Norvasc) have about a 250 percent greater risk of developing some types of breast cancer than other women.
Researchers with the Fred Hutchinson Cancer Research Center in Seattle looked at nearly 3,000 women, 891 of which were cancer-free, 905 of which had been diagnosed with ductal breast cancer and 1,055 of which had been diagnosed with lobular breast cancer. About 40 percent of women in each group was taking or had taken calcium channel blockers for high blood pressure.
