9. Swollen Lymph nodes.
This is the most common symptom of lymphoma. Lymph nodes located in the neck, chest, abdomen and on the skin swell up as a result of this disease. The type of lymphoma that frequently causes swelling of the lymph nodes is called non-Hodgkin lymphoma. It occurs to the lymph nodes situated close to the surface of the body. The enlarged lymph nodes appear as lumps under the skin and are often found by the patient or a health consultant treating the patient. Lymph nodes swelling that occur under the armpits and abdomen usually pose more risk than swelling on other parts of the body. At some point, these lymph nodes become tender and painful but in the case of non-Hodgkin lymphoma, the lymph nodes swell becoming stiff and painless.
