What is non-Hodgkin lymphoma (NHL)?

Non-Hodgkin lymphoma (NHL) is a cancer of the lymphatic system. This is the system that helps protect your body from infection and disease.

The most common symptom of non-Hodgkin lymphoma is a painless swelling in the neck, armpit or groin.

Some types of NHL grow very slowly and may not need treatment for months or years. Other types grow quickly and need treatment soon after diagnosis. 

NHL is the sixth most common cancer in the UK. Around 14,000 people are diagnosed with it each year. It can affect people at any age but is more common as people get older.  Most people diagnosed with NHL are over 55.

Non-Hodgkin lymphoma is 1 of 2 main types of lymphoma. The other type is called Hodgkin lymphoma. How lymphoma develops and the treatment you may need depends on the type of lymphoma.

Causes of non-Hodgkin lymphoma (NHL)

The causes of non-Hodgkin lymphoma are mostly unknown. But some things may increase your risk of developing it. These are called risk factors. 

We have more information about causes and risk factors for NHL.

Diagnosis of non-Hodgkin lymphoma (NHL)

If you have symptoms, you usually start 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, tell your doctor. Some tests and treatments for lymphoma can be harmful to a baby in the womb. If you are pregnant you usually still have tests and treatment for lymphoma. But it is important to talk to your doctor so they can plan your care safely.

Biopsy for lymphoma

The most common test for diagnosing lymphoma is a biopsy. A doctor 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. You may also have biopsies taken from other areas of your body.

You can find out more about further tests you may have in our information about non-Hodgkin lymphoma.

Waiting for test results can be difficult. You may find it helpful to talk to your family, friends or specialist nurse.

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.

For example, your doctor will do blood tests to check the levels of different blood cells in your blood. They may also talk to you about having blood tests to check for certain viruses, such as HIV and hepatitis. 

You may have some of the following tests.

  • CT scan

    A CT scan makes a three-dimensional (3D) picture of the inside of the body using x-rays taken by the CT scanner.

  • Ultrasound

    An ultrasound uses sound waves to build up a picture of internal organs. It can be used to guide a biopsy. The scan helps to guide them to the exact area.

  • PET-CT scan

    A PET-CT scan uses low-dose radiation to check the activity of cells in different parts of the body. It is sometimes given together with a CT scan. This is called a PET-CT scan.

  • MRI scan

    An MRI scan uses magnetism to build up a detailed picture of areas of your body.

  • Bone marrow sample

    A small sample of bone marrow is taken from the back of the hip bone (pelvis). The sample is sent to a laboratory to be checked for abnormal cells.

  • Lumbar puncture

    In some types of non-Hodgkin lymphoma, the lymphoma cells may get into this fluid. A lumbar puncture takes a sample of the fluid that surrounds the brain and spinal cord.

Waiting for test results can be a difficult time, we have more information that can help.

Types of non-Hodgkin lymphoma (NHL)

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.

Stage and grade of non-Hodgkin lymphoma (NHL)

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.

Treatment for non-Hodgkin lymphoma (NHL)

A team of specialists will meet to discuss the best possible treatment for you. This is called a multidisciplinary team (MDT).

There are different types of treatment for NHL. You may need just one type of treatment or a combination of treatments.

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.

Treating lymphoma will depend on:

Types of treatment you may have include:

  • Watch and wait

    During watch and wait, you do not need to start treatment straight away. Instead, you have regular tests and appointments to monitor the lymphoma and check for signs that you need to start treatment.

  • Chemotherapy

    Chemotherapy is often used to treat lymphoma. It uses anti-cancer (cytotoxic) drugs to destroy lymphoma cells. You can have chemotherapy with steroids and targeted therapy drugs.

  • Steroids

    Steroids are drugs given with chemotherapy to help treat lymphoma.

  • Targeted therapies

    Targeted therapies target specific proteins on cells and also encourage the body’s immune system to attack and destroy lymphoma cells. They are given with chemotherapy (called chemoimmunotherapy) or on their own.

  • Radiotherapy

    Radiotherapy treats cancer by using high-energy rays that destroy cancer cells, while doing as little harm as possible to normal cells. It may be used as the only treatment if you have early stage low grade NHL.

  • Stem cell transplant

    Some people may have a stem cell transplant. A stem cell transplant is an intensive treatment, so it is not suitable for everyone. You may have a transplant using:

You may have some treatments as part of a clinical trial.

After non-Hodgkin lymphoma (NHL) treatment

People often have many different feelings when they finish lymphoma treatment. You may feel relieved that treatment has finished, but worried about what will happen in the future. 

You will have appointments with your lymphoma doctor or nurse less often than before. But at the same time, you may have new challenges to cope with and things to think about. 

We have information below about some of the things people ask about after lymphoma treatment. But you may have other questions or need information about something else. If there is something you want to talk about at any point after treatment, you can:

Well-being and recovery

It can take time to recover after lymphoma treatment. Some days you may feel better than others.
