Hodgkin's lymphoma is cancer that affects the lymphatic system, a series of vessels that spreads through the body, according to MayoClinic. It was formerly referred to as Hodgkin's disease.
In people with Hodgkin's lymphoma, cells grow rapidly and abnormally, and these cells may extend to other areas of the body. The condition inhibits the response of the immune system as the cells grow in the body. Its symptoms include itching, fatigue, fever, painless swelling and loss of appetite. Hodgkin's lymphoma can affect teens, people in their 20s and even the elderly who are 70 years or older. The main cause of this condition is not known, but people with poor immune systems have a higher risk of getting the cancer.
