A nurse is providing a community education session about leukemia risk factors. Which statement by a participant indicates a need for further clarification?

A) This choice is incorrect because chronic leukemia can affect both children and adults, not just children and young adults.

B) This choice is incorrect because chronic leukemia progresses more slowly than acute leukemia and does not typically require immediate treatment.

C) This choice is correct. Chronic leukemia is characterized by the overproduction of mature and functional white blood cells. Unlike acute leukemia, the abnormal cells in chronic leukemia are more developed and functional, but they may not function correctly, leading to an accumulation of these cells in the blood.

D) This choice is incorrect because chronic leukemia usually presents with milder symptoms compared to acute leukemia. Hospitalization is not typically required unless complications arise.

A) This statement is correct. Having a family history of leukemia is considered a risk factor for developing the disease, particularly in cases of familial or hereditary leukemia.

B) This statement is correct. Exposure to high levels of ionizing radiation, such as during radiation therapy or nuclear accidents, is a well-known risk factor for leukemia.

C) This statement is correct. Individuals with Down syndrome have an increased risk of developing leukemia, particularly acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML).

D) This statement is incorrect. While physical activity is beneficial for overall health and may reduce the risk of various cancers, there is no evidence to suggest that being physically active specifically reduces the risk of developing leukemia.
