Researchers have recently found that metformin could reduce the possibility of mortality from certain cancers in postmenopausal women living with type 2 diabetes. These findings came after a review of data from about 146,000 postmenopausal women ages 50-79.
When examining specific cancers, it was found that women with diabetes were significantly more likely to develop colon, endometrial, liver, and pancreatic cancers than women without diabetes. It was also found that when women with type 2 diabetes had cancer, the risk of dying was higher than women with cancer without diabetes. However, when women with cancer used metformin to treat their diabetes, the risk of dying from cancer was decreased compared to women who took other drugs for their diabetes.
These findings were published in The International Journal of Cancer on April 15, 2016.
