Researchers at the Weizmann Institute of Science found that sildenafil, the active ingredient in Viagra, may limit the ability of cancer cells to metastasize by altering cholesterol transport.
An analysis of Clalit Health Services data covering 5 million individuals showed a statistical correlation between sildenafil use and improved survival rates among cancer patients.
While the study suggests combining sildenafil with statins could enhance anti-metastatic effects, researchers emphasize that clinical trials are required to prove efficacy in humans.
