Diabetes Drug May Serve as Latest Weapon Against Cancer
The next new cancer treatment may be a 50-year-old diabetes drug.
Scientists say early tests found the drug metformin prevented tumors in mice and reduced the likelihood that diabetics would develop a malignancy.
Metformin is the most commonly used medicine to lower blood sugar and is the subject of about 50 cancer studies globally.
The drug, which sells for about 5 cents a pill, is dispensed about 120 million times each year. If the latest trials on breast and other tumors are successful, the drug could become a cheap weapon in the fight against a myriad of diseases including pancreatic and ovarian cancers.
