Proscar Linked to Breast Cancer in Men

An analysis detailed in UK's Telegraph, 53 men worldwide have developed breast cancer while taking finasteride (Proscar). Finasteride is commonly used for benign prostatic hypertrophy (BPH). Gynecomastia has been a known complication of the medication, but the link to breast cancer has been less certain.

"Patients using finasteride products should be advised to promptly report to their doctor any changes in their breast tissue such as lumps, pain or nipple discharge because these may be signs of a serious condition, such as breast cancer.

"On the basis of the review, it was recommended that a warning on the risk of breast cancer should be included in the product information for all medicines containing finasteride."
