Dairy consumption increases the risk for cancer, according to a study published in BMC Medicine. Researchers compared dairy consumption and cancer risk for over half a million participants in China for 11 years. For every 50 grams (less than a 1/4 cup) of milk and other dairy products consumed per day, overall, liver, and female breast cancer risk increased by 7%, 12%, and 17%, respectively. As more people in China drink milk regularly, intake of saturated fat and hormones associated with cancer development also increase.
