Which of the following statements about prostate cancer is true?

The statement that ethnicity is a risk factor for prostate cancer is true. Research indicates that prostate cancer incidence and outcomes can vary significantly based on ethnic background. For example, African American men have a higher risk of developing prostate cancer and tend to have more aggressive forms of the disease compared to men of other ethnicities. This risk is associated with a combination of genetic, environmental, and lifestyle factors that can contribute to the development and progression of prostate cancer.

Understanding these disparities is crucial for healthcare providers, as it guides screening and prevention strategies tailored to individual risk profiles based on ethnicity. In contrast, the other statements about prostate cancer do not accurately reflect the current understanding of the disease's epidemiology and risk factors.
