Lymphoma

Learn More About Hodgkin's and Non-Hodgkin's Lymphoma

Lymphoma is a generalized term used for cancers that develop in the lymphatic system. Lymphoma cancers currently account for about five percent of all cases of cancer in the United States. One specific type of lymphoma is called Hodgkin's disease. All other lymphatic cancers are grouped together and are known as non-Hodgkin's lymphomas.

The lymphatic system is part of the immune defense system of the human body, and it helps people to fight off diseases and infections. The lymphatic system includes a network of thin tubes that branch into tissues throughout the body. Running along this network of vessels are lymph nodes. Lymph nodes are found in the underarms, groin, neck, chest and abdomen. Other parts of this system are the spleen, thymus, tonsils, and bone marrow.

In non-Hodgkin's lymphomas, cancerous cells in the lymphatic system grow abnormally and rapidly. Tumors, or nodules, begin to grow as a result of this rapid and uncontrolled growth. The cancer cells may then spread to other organs.
