Obesity and Cancer: Is Insulin the Link?

In Uncategorized on August 27, 2012 at 2:02 pm

Studies continue to link obesity with cancers of many types. The question is, what is the linkage? Could it be elevated levels of insulin? If we look at the chemical structure of insulin, it is remarkably similar to growth hormone. Chemicals and hormones that stimulate cancer cells to grow are thought o play a role in the development of recurrence of cancers. Perhaps the fact that most obesity is associated with elevated insulin levels allows the insulin to hyper-stimulate cancer cells, allowing them to flourish?

Alternatively, perhaps it is the elevation of other hormones that stimulates cancer in the obese.A recent study discusses these possibilities in the recurrence of treated breast cancer.
