A new study from Germany shows that dairy product consumption may increase the risk of testicular cancer. Researchers at the University of Halle-Wittenberg tracked dietary contributors to testicular cancer among 269 men with cancer and 797 control subjects. The risk for testicular cancer was increased by 37 percent for those who consumed at least 20 servings of milk per month. The researchers hypothesize that increased galactose (a component of lactose, the milk sugar) and milk fat may explain the association between dairy product consumption and cancer.
