Type 2 diabetes and cancer: umbrella review of meta-analyses of observational studies
Konstantinos K. Tsilidis,Konstantinos K. Tsilidis,John C. Kasimis,David S. Lopez,Evangelia E. Ntzani,John P. A. Ioannidis +5 more
TL;DR: Though type 2 diabetes has been extensively studied in relation to risk of developing cancer and cancer mortality and strong claims of significance exist for most of the studied associations, only a minority of these associations have robust supporting evidence without hints of bias.
