The lymphatic system consists of thin tubes that branch, like blood vessels in all parts of the body. Lymph vessels carry lymph, a colorless, watery fluid containing white blood cells called lymphocytes. Along the network of vessels are groups of small, bean-shaped organs called lymph nodes. Clusters of lymph nodes make and store infection fighting cells.
Spleen (an organ in the upper abdomen that lymphocytes and filters old blood cells from the blood), thymus (a small organ under the sternum) and tonsils (an organ in the throat) is also part of the lymph system.
Since there is lymph tissue in many parts of the body, cancer can spread to almost all body organs or tissues as liver, bone marrow (the spongy tissue inside large bones that makes blood cells), spleen, or brain.
AIDS-related lymphoma is a disease in which cancer (malignant) cells are in the lymphatic system disorders in patients with AIDS (acquired immune deficiency syndrome). AIDS caused by human immunodeficiency virus (HIV) which attacks and weakens the immune system. Infections and other diseases that can penetrate the body and the immune system can not fight them.
Lymphoma is divided into two general types of Hodgkin's disease and non-Hodgkins lymphoma, which is classified by how their cells look under a microscope. This provision is histology. Histology is also used to determine which type of non-Hodgkin lymphoma (many). The types of non-Hodgkin lymphomas are classified by how quickly they spread: low-grade, intermediate quality or high quality. In mid-or high-grade lymphomas grow and spread more quickly than low-grade lymphoma.
The main types of lymphoma, Hodgkin's disease and non-Hodgkin lymphoma can occur in people with AIDS. In mid-and high-grade types of non-Hodgkin's lymphoma usually in AIDS patients. Both forms of lymphoma can also occur in adults and children.
