Non-Hodgkin lymphoma (NHL), sometimes called non-Hodgkin's lymphoma, is a cancer of the lymphatic system. The lymphatic system is part of the body's immune system. NHL develops in white blood cells called lymphocytes.
Non-Hodgkin lymphoma is the fifth most common cancer in the UK. Around 13,500 people are diagnosed with it each year. There are many types of NHL. Some grow very slowly and may not need treatment for months or years. Other types grow quickly and need treatment soon after diagnosis.
We have more information about how non-Hodgkin lymphoma develops.
We also have information about another type of lymphoma called Hodgkin lymphoma.

Doctors do not know the exact causes of NHL. But there are risk factors that can increase your chance of developing it.
Having one or more risk factors does not mean you will get non-Hodgkin lymphoma. Also, having no risk factors does not mean you will not develop NHL.
We have more information about causes and risk factors for NHL.
If you have symptoms, you usually begin by seeing your GP. If they think your symptoms could be caused by cancer, they may arrange for you to have blood tests or scans. Your doctor will refer you to hospital for tests and for specialist advice and treatment.
If you think you may be pregnant, let your doctor know. Some tests and treatments can be harmful to a baby in the womb. Pregnant women can often still have tests and treatments for lymphoma. But, it is important to talk to your doctor so that you can plan your care safely. We have more information about cancer and pregnancy.
Biopsy for lymphoma
The most important test for diagnosing lymphoma is a biopsy. A doctor or nurse will take a sample of tissue from the affected area. The most common place to take a biopsy from is an enlarged lymph node. This is called a lymph node biopsy. You may have all or a part of the lymph node removed. The tissue will be sent to a laboratory for testing.
Further tests for lymphoma
You will have more tests before you start treatment for lymphoma. Some tests help to show the stage of the lymphoma. You may have other tests, such as blood tests or x-rays to check your general health and how well your heart, lungs, liver and kidneys are working.
Information from these tests help your doctors plan your treatment safely and effectively.
You may have some of the following tests:
Bone marrow sample
A lumbar puncture is when a hollow needle is inserted between the bones of the lower back. It is done to take a sample of the cerebrospinal fluid (CSF) that surrounds the brain and spinal cord. In some types of non-Hodgkin lymphoma, the lymphoma cells may get into this fluid.
Waiting for test results can be a difficult time, we have more information that can help.
The results of your tests help your doctors find out how many areas of the body are affected by lymphoma and where these areas are. This is called staging.
Lymphomas are also grouped as either low-grade or high-grade.
We have more information about staging and grading of non-Hodgkin lymphoma.
Types of non-Hodgkin lymphoma
There are many different types of NHL. Your doctors need to know which type you have so they can give you the best treatment.
We have more information about the different types of NHL.
A team of specialists will meet to discuss the best possible treatment for you. This is called a multidisciplinary team (MDT).
Your doctor or cancer specialist or nurse will explain the different treatments and their side effects. They will also talk to you about things to consider when making treatment decisions.
If you have HIV and lymphoma, your lymphoma doctors and HIV doctors will work together to plan your treatment. We have more information about what this might involve.
Treating lymphoma will depend on:
- the type of lymphoma
- and the stage and grade you have.
Types of treatment you may have include:
Watch and wait
Stem cell transplant
There are two types of stem cell transplant. One uses your own stem cells. The other uses stem cells from someone else (a donor). It may be used to treat types of NHL that do not respond well to the most commonly used chemotherapy treatments.
You may have some treatments as part of a clinical trial.
You have regular follow-up appointments after treatment. These appointments are a good opportunity for you to talk to your doctor or nurse about any concerns you have. Your doctor will want to know how you are feeling generally, and to check you are recovering from any side effects of treatment.
Sometimes a side effect may continue or develop months or years after treatment. This is called a late effect.
We have more information about long-term and late effects of treatment for lymphoma.
Everyone has their own way of dealing with illness and the different emotions they experience. You may find it helpful to talk things over with family and friends or your doctor or nurse.
