Lymphoma Report by: Manuel Loggins By definition, lymphoma is a type of cancer involving cells of the immune system, called lymphocytes. Just as cancer represents many different diseases, lymphoma represents many different cancers of lymphocytes, about 35 different subtypes. In fact, lymphoma is a group of cancers that affect the cells that play a role in the immune system and it primarily represents cells involved in the lymphatic system of the body. While lymphomas are often confined to the lymph nodes and other lymphatic tissue, they can also spread almost anywhere in the body to other types of tissue. Lymphoma that’s developed outside of lymphatic tissue is called extra nodal disease. Lymphomas fall into one of two major categories: Hodgkin’s lymphoma, previously called Hodgkin’s disease (HL), and all other lymphomas which are called non-Hodgkin’s lymphomas (NHL’s). These two types of lymphomas occur in the same places, may be associated with the same symptoms, and often have similar appearances on a person’s physical examination. However, they are readily distinguishable via microscope examination. Hodgkin’s disease develops from a specific abnormal B lymphocyte lineage while NHL may derive from either abnormal B or T cells and are distinguished by unique genetic markers. As found in statistics, lymphoma is the most common type of blood cancer in the United States; is the seventh most common cancer in adults; and is the third most common cancer in children. Non-Hodgkin’s lymphoma is far more common than Hodgkin’s lymphoma. In the United States, about 66,000 new cases of NHL and 8,500 new cases of HL were expected to be diagnosed in 2009. Also in 2009, as well as 1,290 deaths were due to HL, with the survival rate of all but the most advanced cases of HL greater than that of other lymphomas. Lymphoma can occur at any age, including
