Lymphoma is a group of cancers involving cells of the immune system. It is believed the cause increases due to infections, autoimmune issues, exposure to toxic chemicals and genetics, although none are proven. Signs that draw attention are swelling in the neck, armpit, groin, or swelling of limbs. Lymphomas fall into two classifications – Hodgkin’s lymphoma and non-Hodgkin’s lymphoma. In 2009, lymphoma cancers affected 74,500 people resulting in 20,790 deaths.
