Learn MoreNon-Hodgkin lymphoma (NHL) is the name for a group of lymphomas that are not Hodgkin lymphoma.
Lymphomas begin in lymphocytes. These white blood cells are part of the body's immune system. They can travel through the body in the bloodstream or in a fluid called lymph that moves through lymph vessels.
Lymph drains into the bloodstream using the body's lymphatic system. This system includes the lymph vessels, lymph nodes, tonsils, thymus, bone marrow, and spleen.
Because lymph travels through the body, lymphoma can start in many places, such as:
Several types of NHL are more common in children. These include:
Signs and symptoms of lymphoma depend on where the disease starts and may include:
The lymphatic system moves lymphocytes to many places in the body.
Risk factors may increase your child’s chances of getting a disease. Little is known about the risk factors for NHL in children. The risk factors we know so far are:
A cancer diagnosis requires tests and procedures. The doctor will give your child a physical exam, take their medical history, and order tests such as:
If the pathologist finds lymphoma cells in the biopsy sample, the lab will perform more lab tests on the sample. These may include flow cytometry, immunophenotyping, and cytogenetic analysis, if these tests are available.
X-ray of pediatric non-Hodgkin lymphoma with evidence of disease.
The care team plans treatment based on the cancer stage. Some tumors grow rapidly, so lymphoma must be staged as quickly as possible.
To find out the stage of NHL, doctors may order more tests such as:
The stage will tell how severe the cancer is, and if it has spread to other parts of the body.
The International Pediatric Non-Hodgkin Lymphoma Staging System divides the diseases into 4 stages:
NHL can be aggressive in children, so treatment must start as soon as possible. More aggressive treatment is needed in higher stages of cancer.
Treatment depends on:
NHL treatment may include:
The treatment plan for some types of NHL depends on how the lymphoma responds when treatment begins. This approach is known as risk-adapted therapy. Doctors choose therapy based on how well cancer responds to treatment.
Your child’s doctor will discuss treatment options with your family.
About 10–30% of NHL patients have a disease that is hard to treat or that comes back after treatment. Treatment options depend on the type of disease and may include:
Some patients may be able to take part in a clinical trial to test a new treatment.
The prognosis for NHL depends on many factors. Your care team is the best source of information about your child's prognosis.
In the United States, about 800 new cases of NHL are diagnosed in children and teens each year. NHLs in children are different from those found in adults. Childhood lymphomas can spread faster to other parts of the body. Yet, these cancers are often highly treatable. Survival depends on individual factors, but the overall survival rate for children and teens in the United States is good (near 90%).
NHL research focuses on:
Coping with a cancer diagnosis and treatment can be stressful for the patient and the family. You may want to talk to a social worker, a psychologist, or another mental health specialist.

After treatment, your child's doctor may use imaging tests and exams to watch for recurrence. Childhood cancer survivors should get long-term follow-up care. Some treatments can cause late effects. These are health problems that happen months or years after the end of their treatment.
After completing treatment, it is important that your child:
