| | Cancer that begins in cells of the immune system.
There are two basic categories of lymphomas. One kind is Hodgkin
lymphoma, which is marked by the presence of a type of cell called the
Reed-Sternberg cell. The other category is non-Hodgkin lymphomas, which
includes a large, diverse group of cancers of immune system cells.
Non-Hodgkin lymphomas can be further divided into cancers that have an
indolent (slow-growing) course and those that have an aggressive
(fast-growing) course. These subtypes behave and respond to
treatment differently. Both Hodgkin and non-Hodgkin lymphomas can occur
in children and adults, and prognosis and treatment depend on the stage and
the type of cancer. |
