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 – African-American men have the highest rate of prostate cancer incidence in the world. Additionally, more advanced prostate cancer is more common in African-American men and because of this they are more than twice as likely to die of prostate cancer as white men. 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 suggesting an inherited or genetic factor. A man whose father or brother has prostate cancer is more than twice as likely to develop prostate cancer. 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.
