Blood Cancers & Disorders

Non-Hodgkin lymphoma begins when a lymphocyte (usually a B cell) becomes abnormal. Because lymphatic tissue is in many parts of the body, Hodgkin lymphoma can start almost anywhere. Usually, it's first found in a lymph node.

Hodgkin lymphoma is a cancer that begins in cells of the immune system. Hodgkin lymphoma can start almost anywhere. Usually, it's first found in a lymph node above the diaphragm, the thin muscle that separates the chest from the abdomen.

Leukemia is cancer that starts in the tissues that forms blood. The types of leukemia can be grouped based on how quickly the disease develops and gets worse. 

Myeloma begins when a plasma cell becomes abnormal. The abnormal cell divides to make copies of itself. The new cells divide again and again, making more and more abnormal cells.
