About radiotherapy for non Hodgkin lymphoma
Radiotherapy uses high energy rays to kill cancer cells. Radiotherapy is often used as a local treatment. You have it when there are lymphoma cells in one or two areas of lymph nodes in one part of the body (stage 1 or 2). You may have radiotherapy with chemotherapy for high grade NHL or if there is a lot of lymphoma. Or you may have radiotherapy after chemotherapy to help stop the lymphoma from coming back.
You usually have radiotherapy treatment once a day from Monday to Friday, with a rest over the weekend. The length of the treatment will depend on the type and size of your lymphoma. Each treatment only takes a few minutes. You can't feel it and it doesn't make you radioactive. So there is no risk to your family or other people when you return home.
Planning your treatment
On your first visit, you lie under a large specialised CT scanning machine. Your treatment team uses the machine to work out exactly where to give the treatment. The doctor will make marks on your skin that the radiographer uses to line up the radiotherapy machine when you have your treatment.
Radiotherapy has 2 main short term side effects. It can cause red, sore skin in the area being treated. And it may make you very tired. If you are having radiotherapy to your brain, as part of a bone marrow transplant or stem cell transplant, you may feel very, very tired. Other radiotherapy side effects vary, depending on the part of the body being treated.
You can view and print the quick guides for all the pages in the Treating NHL section.

You have radiotherapy treatment in the hospital radiotherapy department. Usually, you have treatment once a day from Monday to Friday, with a rest over the weekend. The length of the treatment will depend on the type and size of your lymphoma.
Before you begin your treatment, the radiotherapy team carefully plan your external beam radiotherapy. This means working out how much radiation you need to treat the lymphoma and exactly where you need it. Your planning appointment may take from 15 minutes up to a couple of hours. You will have a planning CT scan. The scan shows the area of the lymphoma and the structures around it.
The 360° photo is of a CT scanner. You can use the arrows to look around the room.
You lie on the scanner couch with the treatment area exposed. The radiographers will put some markers on your skin. You need to lie very still.
Once you are in position the radiographers will move the couch up and through the scanner. The scanner is a doughnut shape. The radiographers leave the room and the scan starts. It takes up to 5 minutes. You won't feel anything. The radiographers watch from the next door room.
Once the treatment team has planned your radiotherapy, they may put ink marks on your skin to make sure they treat exactly the same area every day. They may also make pin point sized tattoo marks in these areas. We have a page about radiotherapy skin markings.
Moulds or masks
If you are having treatment to your head or neck, you may need to have a mould (shell) made to keep you perfectly still while you have treatment. You may also have a mould if you have to keep an arm or leg perfectly still. The moulds are made in the mould room. We have information about making radiotherapy moulds
After your planning session
You may have to wait a few days or up to 2 weeks before you start treatment. During this time the physicists and your radiotherapy doctor decide the final details of your plan. Your doctor will plan the areas that need treatment and outline areas to limit the dose to or avoid completely. They call this contouring. Then the physicists and staff called dosimetrists plan the treatment very precisely using advanced computers.
Radiotherapy machines are very big. The machine may be fixed in one position or able to rotate around your body to give treatment from different directions. Before your first treatment your radiographers will explain what you will see and hear.
The treatment rooms usually have docks for you to plug in music players so you can listen to your own music. You can't feel the radiotherapy when you have the treatment. It takes anything from 1 minute to several minutes. It is important to lie in the same position each time, so the radiographers may take a little while to get you ready.
Once you are in the right position the staff leave you alone in the room for a few minutes. They watch you carefully through a window or on a closed circuit television screen. They may ask you to hold your breath or take shallow breaths during the treatment.
Our page about having external radiotherapy has a video about having radiotherapy that you may want to watch.
External radiotherapy does not make you radioactive. It is safe to be with other people, including children, throughout your treatment.
Radiotherapy has two main short term side effects. It can cause red, sore skin in the area being treated. And it may make you very tired.
The tiredness usually comes on as you go through your course of treatment. It may last for a few weeks after your treatment has finished. Tiredness is an effect of the radiation. And as you have to travel to the hospital daily for the treatment, this builds up after a few weeks. You may find that you need to take a rest during the day from time to time.
If family commitments are going to make it difficult for you to rest, it is worth planning ahead. You will probably need more help as your treatment goes on. There is information about where to get help on the who can help page.
If you are having radiotherapy to your brain, as part of a bone marrow or stem cell transplant, you may become very, very tired. Doctors call this somnolence syndrome. Some people are affected more than others. At its worst, you may be asleep practically all the time for a while but this does wear off.
Other radiotherapy side effects vary, depending on the part of the body being treated. Our radiotherapy section has information about side effects to the

If you would like more information about any aspect of non Hodgkin lymphoma, you can phone the Cancer Research UK nurses on freephone 0808 800 4040. The lines are open from 9am to 5pm, Monday to Friday. They will be happy to answer any questions that you have.
Our non Hodgkin lymphoma organisations page gives details of other people who can provide information about NHL and its treatment. Some organisations can put you in touch with a cancer support group. They often have free factsheets and information which they can send to you. There are also books, booklets, CDs and other resources available. Some of these are free. Look at our NHL reading list for details.
