AIDS-related lymphoma is a disease in which cancer cells form in the lymph system of patients who have acquired immunodeficiency syndrome (AIDS). People with human immunodeficiency virus (HIV) have an increased risk of developing lymphoma and other types of cancer.
Lymphomas are cancers that affect the white blood cells of the lymph system, which is a part of the body's immune system.
There are many different types of lymphoma. Lymphomas are divided into two general types: Hodgkin lymphoma and non-Hodgkin lymphoma. Both Hodgkin lymphoma and non-Hodgkin lymphoma may occur in AIDS patients, but non-Hodgkin lymphoma is more common.
