Non-Hodgkin lymphoma can cause the following symptoms:

• Swollen, painless lymph nodes in the neck, armpits, or groin
• Unexplained weight loss
• Fever
• Soaking night sweats
• Coughing, trouble breathing, or chest pain
• Weakness and tiredness that don't go away
• Pain, swelling, or a feeling of fullness in the abdomen
• Most often, these symptoms are not due to cancer. Infections or other health problems may also cause these symptoms. Anyone with symptoms that do not go away within 2 weeks should see a doctor so that problems can be diagnosed and treated.
