For boys aged 15 to 19, which condition is the fourth-leading cause of death?

• A. Cancer
• B. Suicide
• C. Homicide
• D. Accidents

Answer: (A)

In adolescent boys, death patterns are dominated by external causes, with unintentional injuries being the most common. After that come deaths from violence, including homicide and suicide, which are significant in this age group. Malignant neoplasms, or cancers, are less common than these external causes but still represent a substantial risk, making them the fourth-leading cause of death for boys aged 15 to 19. This category includes cancers such as leukemia and brain tumors, which can be aggressive in teens and require intensive treatment. So cancer fits as the fourth most common cause, given the higher share of deaths from accidents, violence, and self-harm above it.
