Leukemia is a type of cancer that affects the blood cells and bone marrow, and can affect people of all ages. However, it is most commonly diagnosed in children and older adults.
In children, the most common type of leukemia is acute lymphoblastic leukemia (ALL). This type of leukemia is most commonly diagnosed in children between the ages of 2 and 5, but can occur in children of any age. ALL is the most common type of cancer in children, accounting for about one third of all childhood cancers.
In older adults, the most common type of leukemia is acute myeloid leukemia (AML). AML is most commonly diagnosed in adults over the age of 65, but can occur in adults of any age. It is the most common type of leukemia in adults, accounting for about two thirds of all adult cases of leukemia.
Overall, leukemia affects people of all ages, but it is most commonly diagnosed in children and older adults. Early diagnosis and treatment are essential for the best possible outcomes, so it is important for people of all ages to be aware of the signs and symptoms of leukemia and to contact their doctor if they experience any of them.
