Cancer Prevention: What Is the Role of Insulin

It is not a secret that obesity may be a risk factor for cancer. There are multiple explanations for this. Some people say that obesity is creating inflammation, therefore promoting cell transition into cancer cells. Some people think that fat is taking too much of the vitamin D, reducing our natural defense from cancer.

Apparently we may get another clue how obesity hurts our body. For me the news was quite unexpected: Pfizer’s new drug was linked to lung cancer. Guess what drug it is?

It’s the new inhaled insulin Exubera. And no one knows yet how it specifically promotes cancer, but there are studies that suggest the link between insulin and aging. Does insulin alter our immune defense? Is insulin promoting cancerogenesis? At this time there no answers. Maybe it is not insulin itself?

I think we need more studies about insulin and cancer as well as insulin and aging.  My guess is: the more we weigh, the more insulin we produce.  The more obese we are, the higher our chances are to get cancer. Therefore Insulin itself might be the problem.

Bottom line:  want to live longer? Lose weight!
