Hydrochlorothiazide (HCTZ), a diuretic used to treat hypertension, has been linked to an increased risk of squamous cell carcinoma (SCC) in kidney transplant recipients, who are already at heightened cancer risk due to immunosuppression. A study of 2,496 transplant patients revealed a two-fold increased risk of SCC among those exposed to HCTZ, with no significant association found for basal cell carcinoma (BCC). SCC risk, amplified by HCTZ’s photosensitizing effects, highlights the importance of monitoring transplant recipients for skin cancers and considering alternative treatments.
