One particular blood pressure medication has been shown to increased risk of both squamous and basal cell cancer. Long term use of Hydrochlorothiazide, (which is a diuretic commonly used to treat hypertension) has been shown to significantly increase your risk of skin cancer. No other anti-hypertensive medications showed the same association. If you are at high risk for skin cancer and are taking hydrochlorothiazide speak to your doctor to see if there may be a better alternative for you.
