Prostate Cancer: Risk Factors

Three generations of African-American men smiling at the camera

In general, all men are at risk for prostate cancer during their lifetime. However, there are specific risk factors that increase the likelihood for developing the disease.

Age

Aggressive prostate cancer is virtually nonexistent in men under 40. With age, however, the risk of developing prostate cancer increases. According to the American Cancer Society, about 60 percent  of all prostate cancers are diagnosed in men over 65.

Does sexual activity affect my risk of cancer?

For years, men have wondered if sexual activity impacts their risk of prostate cancer. Elizabeth A. Platz, Sc.D., considers the science behind several theories linking sex to prostate cancer. She also reveals the findings of two significant studies designed to put the debate to rest.

See how changes to your sex life could impact your risk.

Race

The Centers for Disease Control and Prevention reports that African-American men have the highest rate of prostate cancer, followed by white, Hispanic, American Indian/Alaska Native and Asian/Pacific Islander men. African-American men are twice as likely to die from prostate cancer as white men, according to the American Cancer Society. Prostate cancer risk may also be elevated in Scandinavian men. Historically, incidence in East Asia (Japan and China) has been low. However, when Chinese and Japanese men immigrate to the U.S., they have an increased risk of developing prostate cancer when compared with their native populations.

Diet

Medical research suggests that the diet consumed in industrialized Western countries may be a factor in developing prostate cancer. Consider the following information regarding diet and its effect on the risk for prostate cancer:

  • Fat: Some studies suggest that men who eat a high-fat diet, especially if it is high in red meat or high-fat dairy products, may have a greater chance of developing prostate cancer.

  • Fruits and vegetables: Diets high in fruits and vegetables may lower prostate cancer risk, although it is not clear which nutrient(s) may be responsible for this.

  • Carotenoids: Carotenoids, such as lycopenes, have been shown to inhibit the growth of human prostate cancer cells grown in the laboratory. The primary source of lycopenes is processed tomatoes. However, it is not clear if lycopenes affect prostate cancer risk in men.

Fruits and vegetables to promote prostate health

How does food affect prostate cancer?

For patients with prostate cancer, researchers are looking for foods or nutrients that boost disease-fighting enzymes and help the body ward off prostate cancer.

Add these to your plate to boost your health and reduce your risk of prostate cancer.

Obesity

Most studies have concluded that obesity does not affect the overall risk of getting prostate cancer. However, obese men may be more likely to develop more aggressive forms of prostate cancer.

Environmental Exposures

Some studies indicate an increased risk of prostate cancer in men who are exposed to certain types of chemicals. For example, firefighters are regularly exposed to combustion byproducts while farmers are exposed to agricultural chemicals. Men in these professions may have an increased risk of developing prostate cancer due to chemical exposure.

Family History

Another important risk factor is a positive family history. If you have a father or a brother with prostate cancer, your risk of developing the disease is more than doubled, according to the American Cancer Society. The risk is developing prostate cancer is even higher for men with several affected relatives, particularly if the relatives were young at the time of diagnosis.
