Prostate Cancer

Dairy Products Linked to Prostate Cancer
A long-term study suggests an association between consumption of dairy products and the risk of prostate cancer. Researchers tracked more than 20,000 male physicians for 11 years and found a moderate elevation in prostate cancer risk associated with higher intake of five dairy products, including milk, cheese, and ice cream.

Men who drank more than six glasses of milk per week had lower levels of vitamin D, which has been shown to protect the prostate. Milk-drinking also raises the amount of insulin-like growth factor (IGF-1) in the blood, which is linked to cancer risk.
