Insulin and Breast Cancer

     A study that was done in China of over 5000 women found that women who had higher levels of circulating insulin that were also postmenopasual had a much higher incidence of breast cancer. Many of these women were thin and not obese, suggesting that weight has nothing to do with it. Thin women in fact had more incidence of breast cancer because thin women tend to have more insulin than overweight women.
