What is "lymphoma"?

Lymphoma is a type of cancer that begins in the lymphatic system, which is part of the body's immune system. It specifically affects lymphocytes, a type of white blood cell that helps fight infections. There are two main types of lymphoma: Hodgkin's lymphoma and non-Hodgkin's lymphoma, each with different characteristics and treatment options. Common symptoms include swollen lymph nodes, fever, night sweats, unexplained weight loss, and fatigue. Treatment typically involves chemotherapy, radiation therapy, immunotherapy, or a combination of these, depending on the type and stage of lymphoma. Early detection and treatment are important for improving the chances of a successful outcome.
