Usually you have intensity modulated radiotherapy (IMRT) for nasopharyngeal cancer. This directs a precisely targeted dose of radiation to the tumour. See how you have it.
What it is
Radiotherapy uses high energy x-rays to kill cancer cells.
You usually have a type of radiotherapy called intensity modulated radiotherapy (IMRT) for nasopharyngeal cancer. IMRT directs a precisely targeted dose of radiation to the area of the tumour from outside the body.
How you have it
You have your treatment in the hospital radiotherapy department.
You go to the hospital for treatment once a day, from Monday to Friday, with a break at the weekends. The length of the course of treatment varies but it is usually between 4 and 7 weeks.
If you smoke, your doctor will advise you to give up before your treatment. Radiotherapy might not work as well and you may have more side effects if you continue to smoke.
The radiotherapy room
Radiotherapy machines are very big and can be daunting at first. Some are fixed in one position, but others rotate around your body.
Before you start treatment your radiographers explain what you'll see and hear. In some departments the treatment rooms have docks for you to plug in music players. So you can listen to your own music.
It is important to lie in the same position each time, so the radiographers may take a little while to position you on the couch and attach your mask to the couch. They make sure your mask feels comfortable.
Once you are in the right position the staff leave you alone in the room.
During the treatment
You need to lie very still. The machine makes whirring and beeping sounds. You can't feel the radiotherapy when you have the treatment.
Your radiographers watch and listen to you on a CCTV screen in the next room. They might ask you to hold your breath or take shallow breaths at times. Tell them if you need to move or want the machine to stop.
The treatment can take between 15 to 30 minutes.
You won't be radioactive
External radiotherapy doesn't make you radioactive. It's safe to be with other people throughout your course of treatment.
Having radiotherapy for head and neck cancer
Daniel (radiographer): Before your treatment starts your doctor will need to work out exactly where the treatment needs to go and also which parts need to be avoided by the treatment.
To have radiotherapy you lie in the same position as you did for your planning scans.
To stop you moving and to make sure your treatment is directed at the cancer you wear a custom mask over your face which is attached to the couch.
We line up the machine using marks on your mask and then leave the room. We control the machine from a separate room this is so we aren’t exposed to radiation.
Treatment takes a few minutes and you’ll be able to talk to us using an intercom. We can see you and hear you while you’re having treatment and we will check that you’re OK.
When your treatment starts you won’t feel anything. You may hear the machine as it moves around you giving the treatment from different angles.
Because we’re aiming to give the same treatment to the same part of the body every day the treatment process is exactly the same everyday so you shouldn’t really notice any difference.
You’ll see someone from the team caring for you once a week while you’re having treatment. They’ll ask how you are and ask about any side effects.
Travelling to radiotherapy appointments
Tell the radiotherapy department staff if you prefer treatment at a particular time of day. They can try to arrange this.
Radiotherapy can make you tired, especially if you have a long journey. You could ask a family member or friend to drive you to the hospital a couple of times a week.
Car parking can be difficult at hospitals. It’s worth asking the radiotherapy unit staff:
- if they can give you a hospital parking permit
- about discounted parking rates
- where you can get help with travel fares
- for tips on free places to park nearby
The radiotherapy staff can usually help to arrange transport for you if you need it. Some hospitals have their own drivers or can arrange ambulances. Some charities offer hospital transport.
