Leukemia is cancer of the blood cells. It forms in tissue such as bone marrow and causes blood cells to be produced and enter the bloodstream. It usually starts in white blood cells, which are strong infection fighters. The blood cells grow and divide abnormally, producing large numbers of white blood cells that do not function properly.
Acute Lymphocytic Leukemia (ALL)
Acute lymphocytic leukemia (ALL), sometimes called acute lymphoblastic leukemia, is a type of cancer that begins in the immature white blood cells in the bone marrow, the hollow space inside of your bones where blood is made. The leukemia cells do not function like normal blood cells, and they grow quickly inside the bone marrow, overtaking the space there.
Acute Myeloid Leukemia (AML)
AML begins in the bone marrow, the soft inner part of certain bones, where new blood cells are made. Changes happen in some of these cells that make them grow out of control. AML usually grows and moves into the blood quickly.
Chronic Lymphocytic Leukemia (CLL)
Chronic lymphocytic leukemia (CLL) is a cancer that begins in B lymphocytes or B cells. These are a type of white blood cell. B lymphocytes are part of the immune system and make antibodies to attack bacteria, viruses, and toxins.
Chronic Myeloid Leukemia (CML)
Chronic myeloid leukemia (CML) is a blood cancer. It begins in myeloid cells which are made in the spongy center of bones (bone marrow).
Healthy myeloid cells form a balance of different blood cells: red cells, some types of white cells, and platelets. In CML, genetic changes cause myeloid cells to produce blood cells that grow out of control.
Lymphoma is a type of blood cancer that develop in the lymph nodes and tissues of the lymphatic system, an important part of the body’s immune system. Lymphomas begin in the white blood cells (lymphocytes) and affect the body’s ability to fight infection. Bone marrow makes red blood cells, blood platelets, and white blood cells. Lymphomas sometimes start from bone marrow lymphocytes.
Hodgkin Lymphoma (HL)
Hodgkin lymphoma (HL) is a blood cancer that begins in a specific type of white blood cells (lymphocytes), which are part of the immune system. HL occurs when a healthy white blood cell becomes abnormal, dividing and making copies of itself in the body.
Non-Hodgkin Lymphoma (NHL)
Non-Hodgkin lymphoma (NHL) is one of the most common cancers in the United States. It accounts for about 4 percent of all cancer cases. More than 95 percent of cases occur in adults but certain types are common among children.
Myeloma is a cancer of the plasma cells, a type of white blood cell that develops in the bone marrow. Plasma cells make antibodies and help the immune system fight off infection and disease. In people with multiple myeloma, the plasma cells become abnormal and produce a protein called an M protein. When these abnormal plasma cells multiply, they can create bone lesions tumors that can cause damage to the bones and lead to pain.
Myeloproliferative Neoplasms (MPNs)
Myeloproliferative Neoplasms (MPNs) are blood cancers that occur when the body makes too many white or red blood cells, or platelets. This overproduction of blood cells in the bone marrow can create problems for blood flow and lead to various symptoms.
Polycythemia vera (PV)
Different health care providers involved in your care may include a hematologist/oncologist, a nurse, a nurse navigator, an oncology social worker or a pharmacist. These people can help you find information and resources that may be useful before, during and after treatment.
In myelofibrosis, scar tissue forms inside the bone marrow. Primary myelofibrosis develops on its own. Secondary myelofibrosis can result from another bone marrow disorder (such as polycythemia vera or essential thrombocythemia). In either case, the body is not able to produce blood cells normally.
Essential thrombocythemia (ET)
Diagnosis of essential thrombocythemia requires blood testing. A complete blood count measures blood cells and platelets. Normal platelet levels are between 150,000 to 400,000 platelets per microliter (μL) of blood. Consistently elevated platelet levels may be a sign of essential thrombocythemia.
