According to the National Cancer Institute, more than 186,000 American men learn they have prostate cancer each year. It is the second most common type of cancer among men in the United States. Only skin cancer is more common. While doctors do not know the exact cause of prostate cancer, research has shown men with certain risk factors are more likely than others to develop the cancer. Some of these risk factors include being over age 65, having a family history of the disease, being African American, and having a condition that causes abnormal prostate cells. However, having a risk factor doesn’t mean that a man will develop prostate cancer. Most men who have risk factors never develop the disease.
