Non-Hodgkin lymphoma can cause many 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.
