Radiotherapy uses high energy x-rays to treat cancer cells. You have the treatment in the hospital radiotherapy department.
When do you have radiotherapy?
Radiotherapy on its own
You might have radiotherapy on its own for stage 1, 2, or 3 non small cell lung cancer if you can’t have surgery because:
- you are not fit enough for surgey
- you have other medical conditions such as heart or lung disease
- your cancer is hard to reach with surgery
Radiotherapy is most often given 5 days a week for between 4 to 7 weeks. However this can vary depending on your cancer. Your specialist will tell you how often you will need to have the treatment.
For a small cancer on the outer part of the lung you might have stereotactic radiotherapy treatment. You usually have it 3 to 8 times over 2 to 3 weeks.
Radiotherapy after surgery
You might have radiotherapy after surgery if your surgeon couldn’t completely remove all of the cancer.
Radiotherapy after chemotherapy
You may have radiotherapy after chemotherapy for stage 2 or 3 non small cell lung cancer. This is called sequential radiotherapy.
Radiotherapy and chemotherapy (concurrent chemoradiotherapy)
You might have radiotherapy at the same time as chemotherapy for stage 2 or 3 non small cell lung cancer. Having both treatments at the same time can increase side effects. You need to be fit and well to have this treatment and might have it as part of a clinical trial.
Radiotherapy to control symptoms
You might have radiotherapy for non small cell lung cancer that has spread to other parts of your body (stage 4). This is called advanced lung cancer.
The radiotherapy room
Radiotherapy machines are very big. They rotate around you to give you your treatment. The machine doesn't touch you at any point.
Before you start your course of treatment your
The radiographers help you to get into position on the treatment couch. You usually need to raise your arms above your head.
The room is darkened and the radiographers line you up in the radiotherapy machine using laser lights and the marks on your skin. You will hear them saying measurements to each other to get you in the right position.
Then the radiographers leave you alone in the room for a few minutes.
During the treatment
You need to lie very still on your back. Your radiographers might take images (x-rays or scans) before your treatment to make sure that you're in the right position. The machine makes whirring and beeping sounds. You won’t feel anything when you have the treatment.
Your radiographers can see and hear you on a CCTV screen in the next room. They can talk to you over an intercom and might ask you to hold your breath or take shallow breaths at times. You can also talk to them through the intercom or raise your hand if you need to stop or if you're uncomfortable.
You won't be radioactive
This type of radiotherapy won't make you radioactive. It's safe to be around other people, including pregnant women and children.
Travelling to radiotherapy appointments
Tell the radiotherapy department if you prefer treatment at a particular time of day. They can try to arrange this.
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
If you have no other way to get to the hospital, the radiotherapy staff might be able to arrange hospital transport for you. But it might not always be at convenient times. To see if you're eligible they usually work it out based on your earnings or income.
Some hospitals have their own drivers or can arrange ambulances. Some charities offer hospital transport.
