Acute lymphoblastic leukemia (ALL) is a rare type of cancer that affects the white blood cells, specifically the lymphocytes. It is estimated that in the United States, about 5,040 people will be diagnosed with ALL in 2021.
ALL is the most common type of childhood cancer, accounting for almost one-third of all cases. However, it is still relatively rare, as only around 3 in every 100,000 children in the United States are diagnosed with it each year.
In adults, ALL is much rarer, as only about 1 in every 100,000 adults are diagnosed with it each year. While ALL can occur at any age, it is most common in adults between the ages of 25 and 44.
Overall, while ALL is a relatively rare type of cancer, it is still an important one to be aware of, as it can affect both children and adults. Early diagnosis is key in order to give patients the best chance of a successful treatment.
