You may develop side effects over the course of your treatment. These usually improve over a few weeks or months after treatment finishes. Your doctor, nurse or radiographer will discuss this with you, so you know what to expect. Tell them about any side effects you have during or after treatment. There are often things that can help.
The side effects of radiotherapy are made worse by smoking. If you smoke, stopping smoking will help. If you want help or advice on how to give up, talk to your clinical oncologist, GP or a specialist nurse. Organisations such as QUIT can also offer advice and support.
