The lymphatic system is parts of the body involved with blood flow and the immune system or how the body fights illness. Lymph nodes are part of this system. 

The two main kinds of lymphoma include:

  • Hodgkin lymphoma, which spreads in a clear way from one group of lymph nodes to another
  • Non-Hodgkin lymphoma, which spreads through the lymphatic system in a way that's not clear

  • Lymphoma is when too many lymph system cells grow and form a lump or mass of abnormal tissue. It's often not clear what causes lymphoma.

  • Symptoms of Hodgkin lymphoma and non-Hodgkin lymphoma include:

    • Swollen lymph nodes
    • Fever
    • Night sweats
    • Feeling tired
    • Loss of weight that's not expected

    These symptoms can happen for other reasons besides cancer. If you have symptoms like those listed above, you should talk to your provider to find out the reason. 

  • There are many ways your doctor may find lymphoma. Your doctor might do one or more of the following:

    • A physical exam
    • A blood test or bone marrow test
    • An imaging test, like an X-ray or bone scan 
    • A biopsy (taking a sample of tissue from your body and testing it) 
    • Ask about your family medical history as well as yours
  • Hodgkin lymphoma and non-Hodgkin lymphoma can happen in children, teens and adults. Less than 100,000 cases are found each year in the United States. 


  • There isn't a known way to stop lymphoma. To stop many kinds of illness, it helps to: 

    • Have a low-fat diet (eating plan) 
    • Eat fruit and vegetables 
    • Get exercise as often as you can
  • How we care for lymphoma depends on many factors: 

    • Type of cancer
    • Size of the cancer
    • Where the cancer is located in the body 
    • Stage of cancer 

    Your doctor will work with you to find the right care plan for you. Some examples of treatment include:

    • Surgery to remove cancer 
    • Chemotherapy (using medication to make the cancer smaller or to kill cancer cells)
    • Radiation (using X-rays to kill cancer cells)
    • Cryosurgery (using cold temperatures to freeze or kill cancer cells) 
    • Targeted therapy (using drugs to stop cancer cells from growing and spreadin
