Chronic lymphocytic leukemia (CLL) is more likely to occur in which group?

Chronic lymphocytic leukemia (CLL) is indeed more prevalent in older adults, particularly men over the age of 60. This demographic is at a higher risk due to several factors including age-related changes in the immune system and the accumulation of genetic mutations that can lead to the disease. In general, CLL is rare in younger individuals and most commonly diagnosed in older adults, reflecting the relationship between age and the environmental or genetic factors that contribute to its development.

The tendency for CLL to predominantly affect older adult males can also be seen in the statistics, which show a significantly higher incidence in men compared to women. This distinctive pattern aligns with the pathophysiology of CLL, where the malignant proliferation of B lymphocytes leads to the gradual accumulation of these cells over time, facilitating the progression of the disease as individuals age.

That makes the option regarding men over 60 the most suitable and accurate choice for identifying the group in which chronic lymphocytic leukemia is most likely to occur. The other groups mentioned, such as women under 30 and children under 12, have a significantly lower incidence of CLL, as this disease does not manifest commonly outside of older adults. Young adults also fall into a demographic that tends not to
