Lymphoma affects the lymphatic system, which exists throughout the body and plays a major role in immune function. It comprises a network of fluid, lymphocytes, lymphatic vessels, lymph nodes and lymphatic organs, such as the spleen, thymus, tonsils, and bone marrow, as well as in the stomach, intestines, and skin. There are several types and subtypes of lymphoma cancer, and most can be classified as either Hodgkin lymphoma (which account for ten to 15% of cases) or non-Hodgkin lymphoma.
Ordinarily, tenderness accompanies inflamed lymph nodes, especially those caused by an infection. However, people with early-stage lymphoma do not usually experience pain. The swelling may develop in the neck, armpits, or groin, locations with a high concentration of lymph nodes. This symptom alone is not always enough to prompt an individual to seek medical attention.
