How Blood Pressure Meds Increase Lip Cancer Risk



Recent Studies and their Results

The November California Dental Association Journal reports that according to a recent study in Archives of Internal Medicine, the risk for lip cancer increases with long-term use of antihypertensive drugs.
Researchers identified 712 patients with lip cancer compared to 22,904 matched individuals.  The lip cancer group was taking antihypertensive drugs hydrochlorothiazide and nifedipine.  These drugs are photosensitizing--they create greater sensitivity to sun exposure, especially with long term use.
It would seem a good idea, then, to use a lip balm with an adequate SPF rating, not only for moisture but also for disease prevention.
