Lymphoma is a type of cancer that originates in lymphocytes of the immune system. They often originate in lymph nodes, presenting as an enlargement of the node (a tumour).
“Survivor” winner Ethan Zohn is battling cancer, according to a report in People magazine.Zohn was diagnosed with the disease after months of itching and night sweats. While doctors originally thought it to be a skin condition, they discovered a swollen lymph node and a mass on the side of his left chest. Eventually, his condition was determined to be CD20-positive Hodgkin’s Lymphoma.
Lymphomas are closely related to lymphoid leukemias, which also originate in lymphocytes but typically involve only circulating blood and the bone marrow (where blood cells are generated in a process termed haematopoesis) and do not usually form tumours.There are many types of lymphomas, and in turn, lymphomas are a part of the broad group of diseases called hematological neoplasms.
The most common symptom of non-Hodgkin's lymphomas is a painless swelling in the lymph nodes of the neck, underarm, or groin. Other symptoms may include fevers, night sweats, tiredness, weight loss, itching, and reddened patches on the skin. Sometimes there is nausea, vomiting, or abdominal pain.
As lymphomas progress, the body is less able to fight infection. These symptoms are not sure signs of cancer, however. They also may be caused by many common illnesses, such as the flu or other infections. But it is important to see a doctor if any of these symptoms lasts longer than 2 weeks.
