What are the three leading cancer sites among white American males?

1. Prostate, lung, and liver

2. Prostate, colorectal, and lung

3. Colorectal, pancreatic, and skin

4. Lung, colorectal, and kidney

The correct answer is: Prostate, colorectal, and lung

The leading cancer sites among white American males are indeed prostate, colorectal, and lung. This classification aligns with the statistical data reported on cancer incidence in the United States. Prostate cancer is the most commonly diagnosed cancer among males, and its prevalence is significant due to both genetic factors and screening practices. Colorectal cancer consistently ranks high as well, often attributed to lifestyle factors, diet, and screening behaviors. Lung cancer remains a leading cause of cancer death and incidence, primarily linked to smoking and exposure to carcinogens. This specific combination of cancers—prostate, colorectal, and lung—reflects the trends reflected in national cancer databases and registries, providing a clear understanding of the most prevalent cancers for this demographic group.
