Can too much calcium increase my risk of prostate cancer?

Dariush Mozaffarian, MD
Internal Medicine
There is good evidence that a high intake of calcium increases the risk of prostate cancer. One study found that men who consumed more than 2,000 mg of calcium daily were five times as likely to develop metastatic prostate cancer as those who consumed less than 500 mg of calcium per day. A large epidemiologic study found that intake of more than 1,500 mg of calcium per day might increase the risk of aggressive and fatal prostate cancer, but not the risk of less aggressive, localized cancer. So men should avoid taking calcium supplements and be careful not to consume too many dairy products.
