Those medications your doctor prescribes may have more than 1 benefit
Metformin which is a common diabetes medication has seen some observational link to lower risk for liver cancer. This is assuming that it is accompanied with taking the medication as prescribed and having good sugar control. More to come on this as it gets looked at closer. But pretty cool to be on a medication that will help your sugars and protect against cancer, (its also associated with weight loss effects). WIN WIN WIN.
