Hematologic Cancers (Blood System Cancers)

Leukemia, Hodgkin's Lymphoma, Non-Hodgkin's Lymphoma and Multiple Myeloma


Leukemia is a group of cancers that affects the blood and the bone marrow—the soft tissue inside the bone where blood cells are formed. Leukemia leads to an uncontrolled increase in the number of immature white blood cells or blasts.

Over time, these cancerous blast cells fill up the bone marrow and prevent healthy red cells, platelets, and mature white cells from being produced. Leukemia is divided into two major types: acute bone cancer, which grows rapidly, and chronic cancer, which progresses more slowly. Among these, the four most common types of leukemia include:

  • Acute lymphocytic leukemia (ALL)

  • Acute myelogenous leukemia (AML)

  • Chronic lympocytic leukemia (CLL) and

  • Chronic myelogenous leukemia (CML)


Lymphomas are cancers of the lymph glands and lymphatic system. The two main types of lymphoma cancer are Hodgkin's lymphoma and non-Hodgkin's lymphoma. According to the Leukemia and Lymphoma Society, about 628,000 people are currently living with lymphoma or are in remission.

Hodgkin's lymphoma can occur in both children and adults and is one of the most curable forms of cancer. Hodgkin's lymphoma commonly affects lymph nodes in the neck or in the area between the lungs behind the breastbone. Hodgkin's lymphoma can also begin in groups of lymph nodes under the arms, in the abdomen, or in the groin.

Non-Hodgkin's lymphoma is more common. Non-Hodgkin's lymphoma refers to a variety of cancers involving the lymph system and can begin in any part of the body, not just the lymph nodes.  Learn about treatments for Hodgkin's and non-Hodgkin's lymphoma.

Multiple Myeloma

Multiple Myeloma is a cancer of the plasma cells in the bone marrow. When these plasma cells grow out of control and form bone tumors, they can cause pain and destruction of the bones, and make it more difficult for the bone marrow to make red blood cells, white blood cells and platelets. Learn about treatments for multiple myeloma.

Blood cancer treatments depend on a number of factors, including the type and stage of cancer, as well as the patient’s health and age.
