@afrobin Certainly there may be co-founding explanations for the link between type 2 diabetes and cancer but, if you look at the peer reviewed research, it is established that type 2 diabetes increases the risk of several cancers - and likely there is direct metabolic connection.Type 2 diabetes increases the risk for endometrial, liver, and pancreatic cancers ( may double the risk). It also increases the risk of bladder, breast, non-Hodgkin lymphoma and colorectal cancer.
