Can Sildenafil (Viagra) Slow Cancer Metastasis? What the 2026 Study Actually Found Quick Answer A 2026 study found that sildenafil, the active ingredient in Viagra, reduced cancer-cell migration and metastatic burden in multiple experimental cancer models. The proposed mechanism involves disrupting how cancer cells move cholesterol out of lysosomes, leaving less cholesterol available for processes linked to metastasis. Adding statins produced an additive anti-metastatic effect in the study by also limiting cholesterol synthesis. Researchers also found an association between sildenafil use and better survival in retrospective health-record data, but that does not prove the drug caused the improvement. Sildenafil is not currently an FDA-approved treatment for preventing or treating cancer metastasis. A familiar erectile dysfunction drug is attracting attention for a completely different reason. In July 2026, researchers reported that silden...
