What causes prostate cancer?

ANSWER

Doctors don’t know what causes prostate cancer, but diet contributes to the risk. Men who eat lots of fat from red meat are most likely to have prostate cancer. Eating meat may be risky for other reasons: Meat cooked at high temperatures produces cancer-causing substances that affect the prostate. The disease is much more common in countries where meat and dairy products are common than in countries where the diet consists of rice, soybean products, and vegetables.

Hormones also play a role. Eating fats raises the amount of testosterone in the body, and testosterone speeds the growth of prostate cancer.

A few cancer-related job hazards have been found. Welders, battery manufacturers, rubber workers, and workers frequently exposed to the metal cadmium seem to be more likely to get prostate cancer.

Not exercising also makes prostate cancer more likely.
