Metformin May Treat Ovarian Cancer, Mayo Clinic Study

Diabetic patients with ovarian cancer who took the drug metformin for their diabetes had a better survival rate than patients who did not take it, a study headed by Mayo Clinic shows. The findings, published early online in the journal Cancer, may play an important role for researchers as they study the use of existing medications to treat different or new diseases. Metformin is a widely prescribed drug to treat diabetes, and previous research by others has shown its promise for other cancers. The Mayo-led study adds ovarian cancer to the list.
