Final answer:
Lymphoma is a type of cancer that affects the cells of the immune system, specifically the lymphocytes. There are two main types of lymphoma: Hodgkin lymphoma and non-Hodgkin lymphoma, each with distinct characteristics and treatment approaches.
Step-by-step explanation:
Lymphoma is a type of cancer that affects the cells of the immune system. It specifically targets the lymphocytes, which are a type of white blood cell involved in immune responses. Lymphomas can develop in various parts of the lymphatic system, such as the lymph nodes, bone marrow, spleen, and thymus.
There are two main types of lymphoma: Hodgkin lymphoma and non-Hodgkin lymphoma. Both types involve abnormal growth of lymphocytes, but they have distinct characteristics and require different treatment approaches.
Hodgkin lymphoma is characterized by the presence of Reed-Sternberg cells, which are large abnormal cells found in the affected lymph nodes. Non-Hodgkin lymphoma encompasses a broader group of lymphomas, with various subtypes and characteristics.
