A Canadian study has found a common medication to treat Type 2 diabetes could help prevent ovarian cancer. Published in the medical journal Clinical Cancer Research, the study claims the drug metformin may be able to stop and possibly reverse scarring of the ovaries that occurs with age. Lead author Curtis McCloskey says the primary risk factor for ovarian cancer is the number of ovulations a woman has throughout her lifetime. McCloskey says most of the ovaries from post-menopausal women were fibrotic, meaning scarred. In a surprise discovery, the team discovered one woman with Type 2 diabetes who had a long history of taking metformin, also had one youthful-appearing ovary. McCloskey hopes to see scientists go further by giving women metformin for a year to see if the fibrosis goes away.
