Hodgkin's disease is one of the rarer varieties of cancer that affects the body's immune system. In particular, it strikes the lymph nodes. These have a key role to play helping fight off infection so when they are damaged the body becomes exposed to a range of illnesses. Usually, Hodgkin's lymphoma causes a swelling in the neck or the armpits and groin. The swelling is not painful, but it demands immediate medical intervention.
Statistics show that this disease is most likely to appear in the early 20's or elderly people. It also appears to be a little more common in females. Scientists are unsure about the exact causes, but figures show that there is certainly a genetic element that increases risks, and it could also develop if the immune system is weakened because of another condition, or if a person has previously suffered from glandular fever.
