Viagra May Slow Cancer Spread by Trapping Cholesterol, Study Finds

Sildenafil (Viagra) appears to disrupt cholesterol trafficking in cancer cells, limiting their ability to spread in mouse models of breast, lung, and colon cancer, while a retrospective analysis of health records from over 40,000 male cancer patients linked combined sildenafil and statin use to about a 31% lower five-year mortality versus neither drug. The results are observational and require clinical trials to confirm causality.
