What are the risk factors for prostate cancer?

• A. Old age and African American
• B. African American
• C. Young age
• D. High-fat diet

Answer: (A)

Prostate cancer risk rises with age, and race also influences risk, with African American men having a higher incidence and mortality than men of other races. The combination of old age and being African American captures two of the strongest, well-supported risk factors, making it the best answer.

Most cases are diagnosed in men 65 and older, so age is the dominant factor. African American men face higher risk independent of age, likely due to a mix of genetic factors and disparities in screening and access to care.

Young age is not a risk factor; high-fat diet’s link to prostate cancer is not as strongly established as age and race, so it’s not as good a predictor in this context.
