Prostate cancer is the most common non-skin cancer in America, affecting 1 in 6 men. The older you are, the more likely you are to be diagnosed with prostate cancer. Although only 1 in 10,000 under age 40 will be diagnosed, the rate shoots up to 1 in 39 for ages 40 to 59, and 1 in 14 for ages 60 to 69. In fact, more than 65% of all prostate cancers are diagnosed in men over the age of 65.

But the roles of race and family history are important as well. African American men are 61% more likely to develop prostate cancer compared with Caucasian men and are nearly 2.5 times as likely to die from the disease. Men with a single first-degree relative—father, brother or son—with a history of prostate cancer are twice as likely to develop the disease, while those with two or more relatives are nearly four times as likely to be diagnosed. The risk is even higher if the affected family members were diagnosed at a young age, with the highest risk seen in men whose family members were diagnosed before age 60.

Although genetics might play a role in deciding why one man might be at higher risk than another, social and environmental factors, particularly diet and lifestyle, likely have an effect as well.

In fact, research in the past few years has shown that diet modification might decrease the chances of developing prostate cancer, reduce the likelihood of having a prostate cancer recurrence, or help slow the progression of the disease.  When weighing risk factors for prostate cancer, it’s also important to recognize that there are non-risk factors, or factors that have not been linked to an increase in risk.
