Immune or autoimmune disorders that can cause swollen
lymph nodes include rheumatoid arthritis and HIV. Cancers that can cause swollen
glands include leukemia, Hodgkin's disease, or non-Hodgkin's lymphoma.
Which lymph nodes are swollen depends on the type of problem and the body parts involved. Identifying the location can help determine the possible cause.
Swollen lymph nodes may also be caused by some medications (like phenytoin for seizures) or certain vaccinations (namely, typhoid).
