Non-Hodgkin Lymphoma (NHL) is a type of cancer that affects the lymphatic system, which is part of the body's immune system. Unlike Hodgkin lymphoma, NHL includes a diverse group of blood cancers that can develop in lymph nodes, spleen, or other organs. Symptoms may include swollen lymph nodes, fever, weight loss, and fatigue. There are many subtypes of Non-Hodgkin Lymphoma, each with different characteristics and treatment options. Doctors often use chemotherapy, radiation therapy, or targeted therapies to treat NHL. Early diagnosis and treatment are crucial for improving outcomes and managing the disease effectively.
