| Coloured computed tomography (CT) and positron emission tomography (PET) composite axial scan of the trunk of a 25 year old man with Hodgkin lymphoma. Hodgkin disease is a rare form of cancer, where B-lymphocytes (a type of white blood cell) start to multiply abnormally and collect in parts of the lymphatic system. Multiple damage to the lymph nodes of the spleen and spine are seen (red). The cancer has been highlighted using the radioactive label fluorodeoxyglucose (18F-FDG). Cancerous cells show up brighter than normal cells because they are more active and take up more glucose. The most common symptom is a painless swelling in a lymph node, usually in the neck, armpit or groin. The cause of this cancer is still unclear, but it is more prevalent in individuals aged 20 to 40 or over 75 and affects slightly more men and those with a weakened immune system. Hodgkin lymphoma can be successfully treated with chemotherapy and radiotherapy. | |
