Final answer:
Hodgkin's lymphoma affects B cells and has different subtypes. It is important to determine the type for treatment. Symptoms include lumps, weight loss, and night sweats.
Step-by-step explanation:
Hodgkin's lymphoma is a type of lymphoma which affects the lymphocytes, specifically the B cells. It is one of the two major types of lymphoma, with non-Hodgkin lymphoma being more common. Hodgkin's lymphoma has about 60 different subtypes, depending on which specific cells are affected and how.
It is important to determine the type of lymphoma in order to choose the best course of treatment. This is done by examining and testing the biopsied tissue to identify the affected cell types and specific cell-surface proteins called antigens.
Signs and symptoms of Hodgkin's lymphoma include lumps or swelling (tumor), enlarged lymph nodes, cough, weight loss, fatigue, and night sweats. Prompt treatment is necessary for Hodgkin's lymphoma, but with early detection and proper treatment, about 70% of patients can be cured.
