Lymphoma is a type of cancer that begins in the infection-fighting lymphocytes of the immune system. Lymphoma cancer cells can grow in any part of the lymphatic system, including the spleen, the bone marrow, thymus, lymph nodes, or any other part of the body. visit our website for more information on Lymphoma cancer : https://doctorpkdas.com/

Non-Hodgkin lymphoma (also known as non-Hodgkin's lymphoma, NHL, or sometimes just lymphoma) is a cancer that starts in cells called lymphocytes, which are part of the body's immune system. Symptoms depend on what area of the body is affected by the cancer and how fast the cancer is growing.
