Internal radiotherapy for lung cancer
This page tells you about internal radiotherapy for lung cancer. There is information about
What internal radiotherapy is
Internal radiotherapy is called brachytherapy or endobronchial therapy. The radiotherapy is given inside the lung airway. It is sometimes used when a tumour is blocking your airway. It can shrink the blockage to help make your breathing easier and quieter. It can also help control infections and bleeding caused by the tumour. Radiotherapy given this way can be repeated 2 to 3 times.
Having the internal radiotherapy treatment
Having this treatment is similar to having a bronchoscopy. You usually have a local anaesthetic and a sedative. A tube called a bronchoscope is put into your windpipe, either through your nose or your mouth.
A thin tube called a catheter is put through the bronchoscope and into your lung. The doctor then puts a radioactive source down the catheter and positions it next to the tumour. The source is a radioactive metal and gives a dose of radiation to a small area around it. It is left in place for a few minutes. The treatment does not hurt.
With internal radiotherapy, most of the radiotherapy dose will go straight to the cancer and very little will go to healthy tissue. This means there are few side effects. Your throat may feel a bit sore for a few days. And you may find you have a cough and produce more phlegm temporarily.
Internal radiotherapy is also called brachytherapy or endobronchial therapy. The radiotherapy is given from inside the lung airway. It is sometimes used when a tumour is blocking, or partly blocking, your airway. If an airway is blocked this can make you feel breathless and may cause a particular type of noisy breathing called stridor.
Internal radiotherapy can shrink the blockage to help make your breathing easier and quieter. It can also help to control infections and bleeding caused by the tumour. You might have internal radiotherapy in combination with other treatments to relieve a blocked airway.
Radiotherapy given in this way can be repeated 2 or 3 times if necessary.
Having this treatment is similar to having a bronchoscopy. You are likely to have had a bronchoscopy when you were diagnosed. A bronchoscopy is a way of looking at the inside of the airways. You are usually given a local anaesthetic and a sedative. The doctor then puts a long, thin, flexible tube called a bronchoscope either down your nose, or into your mouth and into your windpipe.
This can be a bit uncomfortable, but it doesn't last long and you will have a local anaesthetic. The doctor puts a thin tube called a catheter down the bronchoscope so it is close to the tumour. They then take the bronchoscope out and put a radioactive source down the catheter. The source is a radioactive metal and gives a dose of radiation to a small area around it. It is left in place for a few minutes. The treatment does not hurt. The doctor then takes out the radioactive source and catheter. Once the radioactive source is out you are not radioactive so it is safe to be with other people.
The radioactive source only gives radiotherapy to a very small area inside your airway. This means that there are few side effects. Your throat may feel a bit sore for a few days after the treatment. If you are having it to relieve a blockage in your airway you may find that you have a cough and produce more phlegm temporarily.
