The second way in which the condition is classified is by the type of cells affected. There are four main types of leukemia, based on whether they are acute or chronic, and myeloid or lymphocytic:. Other rare types of leukemia include hairy cell leukemia, myelodysplastic syndromes and myeloproliferative disorders. The Malignant Hematology Program at Moffitt Cancer Center specializes in the evaluation and comprehensive treatment of patients with all types of hematologic diseases, including leukemia.
As a high-volume cancer center, Moffitt offers state-of-the-art testing techniques, highly specialized diagnostic services and evidence-based approaches to treatment.
Additionally, each patient case is reviewed by a multispecialty tumor board to ensure the best possible treatment and supportive care. To learn more about Moffitt and our treatments for various types of leukemia, call or complete a new patient registration form online.

It affects close to 45, people in the United States each year. Leukemia is the most common type of blood cancer in people older than Leukemia occurs when abnormal white blood cells in the bone marrow quickly increase and destroy normal blood cells.
This leaves a person prone to infection. Treatment approaches for leukemia depend on the type of white blood cell affected and whether the disease is acute or chronic. Acute leukemia forms rapidly and becomes severe quickly.
Chronic leukemia grows more slowly and takes longer to advance. This type of leukemia begins in the B or T lymphocytes , which are immature white blood cells. Lymphocytes are the building blocks of the lymphoid tissues that make up the immune system. Doctors further sub-classify ALL based on the variety and developmental stage of the lymphocyte involved. It tends to progress quickly.
It can affect any component of the blood and there are many subtypes of AML. In AML, myeloid stem cells usually mature into abnormal myeloblasts, or white blood cells. But, they sometimes become abnormal red blood cells or platelets.
As they multiply, they overwhelm the normal cells in the bone marrow and blood. The cancer cells can also spread to other parts of the body.
CLL accounts for about a third of leukemia diagnoses. It usually affects older adults. One form of CLL progresses slowly. Symptoms may not appear until years after onset. Another form of CLL grows very quickly. CLL begins in the B lymphocytes. As the abnormal cells proliferate, they crowd out the normal cells. This type of leukemia is rare. Only 10 percent of leukemias are CML. CML occurs when a genetic change turns the myeloid cells into immature cancer cells.
These cells then grow slowly and overwhelm the healthy cells in the bone marrow and blood. A rare type called hairy cell leukemia HCL — because of how it looks under a microscope — affects fewer than 6, people each year. Prognosis — or chance of recovering from leukemia — depends on many factors. Leukemia subtypes fall along a continuum for projected outcomes, but individual cases can deviate from these predictions. Due to a national shortage of blood collection tubes, you may experience upwards of a 2-hour delay in processing time for certain tests.
Someone from our team will advise you if your scheduled lab test is affected by this delay. We thank you in advance for your patience. Types of Leukemia The types of leukemia also can be grouped based on the type of white blood cell that is affected. It accounts for more than 15, new cases of leukemia each year.
Most often, people diagnosed with the disease are over age
