I am not a scientist. I think a blind study on type 2 diabetes people should be done before anyone believes anything out of the mouth of a drug company. What is the cancer rate among Type 2 diabetes, and the general population. What is the cancer rate between people with type 2 diabetes using Metformin, and those that do not? And doctors need to stop giving high blood pressure pills to type 2 diabetes people, unless they emphatically warn their patient that those pills may damage your kidneys, and let the type 2 diabetes person know how many of them suffer kidney problems.
