Which demographic is at highest risk for chronic lymphocytic leukemia?

• A. Females >70, Asian
• B. Males >50, Caucasian
• C. Children under 10
• D. Males <20

Answer: (B)

Chronic lymphocytic leukemia is most common in older adults, with risk increasing with age. It also shows a male predominance and is more frequent in people of European (Caucasian) descent than in Asians or Africans. Among the options, older males who are Caucasian fit the highest-risk group. The other groups—females of advanced age, children, or younger males—have markedly lower incidence of CLL.
