Lymphomas are cancers that develop in the lymphatic system --
the tissues and organs that produce, store, and carry white
blood cells. The lymphatic system includes the bone marrow,
spleen, thymus, lymph nodes, and a network of thin tubes that
carry lymph and white blood cells into all the tissues of the
body. Types of lymphoma include non-Hodgkin's, Hodgkin's, and
cutaneous T-cell lymphoma. In non-Hodgkin's lymphoma, the most
common form of the disease, cells in the lymphatic system become
abnormal. They divide and grow without any order or control, or
old cells that should die, don't. Non-Hodgkin's lymphoma can
begin or spread to almost any part of the body. In Hodgkin's
disease, cells in the lymphatic system also become abnormal, but
the cancer tends to spread in a fairly orderly way from one
group of lymph nodes to the next. Eventually, it can spread
almost anywhere. In cutaneous T-cell lymphoma, T-lymphocytes
(infection fighting white blood cells) become cancerous, causing
skin problems. Lymphoma is acco
