Prostate Cancer - Causes and Risk Factors
- Age - The most common risk factor for prostate cancer is age. The incidence of prostate cancer increases greatly after age 50. Nearly 2 out of 3 prostate cancers are found in men over the age of 65.
- Race – Black men in the US and Caribbean have the highest rates of prostate cancer in the world. For reasons that still remain unclear, African American men have a 74% higher chance of being diagnosed with prostate cancer and are more than twice as likely to die of prostate cancer as white men(American Cancer Society. Cancer Facts & Figures 2018. Atlanta: American Cancer Society; 2018). . Non-Hispanic whites are more likely to be diagnosed with prostate cancer than Asian-American and Hispanic/Latino men. The reasons are unclear for these racial and ethnic differences.
- Genetic - Prostate cancer appears to run in some families, which suggests there may be an inherited or genetic factor. A man whose father or brother has prostate cancer is more than twice as likely to develop the disease. The risk is much higher for men with several relatives affected by prostate cancer, especially if their relatives were young at the time the cancer was found. Men who have been diagnosed with BRCA1 and BRCA2 mutations have a higher risk of prostate cancer.
