It's common to feel very tired towards the end of your course of radiotherapy treatment.
The tiredness may last for weeks or months after the treatment has ended. It can sometimes go on for a year or two although this is rare.
Sometimes tiredness can be minimised by carefully planning your day, getting help with jobs in the house and making sure you sleep well. It's important to allow yourself time to recover after the treatment and not try to do too much too quickly.
Light to moderate exercise every day can help you feel better and can give more energy, although you may feel so tired that doing any exercise seems overwhelming. Many people with cancer can get 'out of condition' while they are going through treatment and when they are recovering afterwards.
One of the best ways to feel more energetic is to build up the amount of exercise you do. Just a short walk every day can help. You can try to increase the distance you go each time. Your doctor or nurse can give you information about exercise.
You may find it helpful to read our sections on fatigue| and exercise after cancer treatment|.
