Key Statistics for Acute Lymphocytic Leukemia

The American Cancer Society’s estimates for acute lymphocytic leukemia (ALL) in the United States for 2018 (including both children and adults) are:

  • About 5,960 new cases of ALL (3,290 in males and 2,670 in females)
  • About 1,470 deaths from ALL (830 in males and 640 in females)

The risk for developing ALL is highest in children younger than 5 years of age. The risk then declines slowly until the mid-20s, and begins to rise again slowly after age 50. Overall, about 4 of every 10 cases of ALL are in adults.

The average person’s lifetime risk of getting ALL is less than 1 in 1000. The risk is slightly higher in males than in females, and higher in whites than in African Americans.

Most cases of ALL occur in children, but most deaths from ALL occur in adults. Children may do better because of differences in childhood and adult ALL in the disease itself, differences in treatment (children’s bodies can often handle aggressive treatment better than adult’s), or some combination of these.
