“The distribution of blood cancer cases reveals patterns across age, sex, and race. The risk for most blood cancers increases as people get older, though some types are more prevalent in younger populations. Leukemia is the most common cancer in children, accounting for 28% of all childhood cancers, with the risk for acute lymphoblastic leukemia (ALL) highest in those under five.

Blood cancers are statistically more common in men than in women. For example, 2021 estimates for acute myeloid leukemia (AML) showed an incidence rate of 5.2 per 100,000 for males compared to 3.5 per 100,000 for females.

There are also notable variations among racial and ethnic groups. Multiple myeloma is more than twice as common in African Americans as it is in White Americans. In contrast, chronic lymphocytic leukemia (CLL) is more frequently diagnosed in North America and Europe than in Asia. Hispanic children and adolescents have higher incidence rates of leukemia compared to other groups in the U.S.”
