Leukemia is either acute or chronic and can arise in either of the two main types of white blood cells — lymphoid cells or myeloid cells. Acute lymphocytic leukemia is the most common type of leukemia in young children, but it also affects adults, especially those 65 and older. Acute myeloid leukemia occurs in both adults and children. Chronic lymphocytic leukemia most often affects adults over the age of 55 and almost never affects children. Chronic myeloid leukemia occurs mainly in adults.

Diagnosis
The doctor will conduct a thorough physical exam and review your medical history. Blood and bone marrow tests may also be administered. A bone marrow biopsy is performed with a larger needle and removes a small piece of bone and bone marrow. A spinal tap checks for leukemia cells in the fluid that fills the spaces in and around the brain and spinal cord. X-rays can reveal signs of the disease in the chest.
