C82.4: Follicular lymphoma grade IIIb
Follicular lymphoma grade IIIb is a type of non-Hodgkin lymphoma, which is a cancer that originates from white blood cells, called lymphocytes, in the lymphatic system. This specific form of lymphoma is characterized by fast-growing tumors predominately composed of large cells. Most commonly, it affects lymph nodes, but it can also invade other organs like the spleen or the digestive tract. Symptoms typically include painless swelling of the lymph nodes, fever, weight loss, fatigue, and night sweats. The progression of the disease is often gradual, with periods of relative stability alternated with times of rapid growth. The name 'follicular' refers to the growth pattern of the cancer cells, which form clumps known as 'follicles'. Although it's known to be related to genetic changes and possibly certain viruses, the exact causes of follicular lymphoma grade IIIb are still unclear.
