Radiotherapy can be used to eradicate cancer cells or alleviate upsetting symptoms and improve quality of life.

Why does radiotherapy make you tired?

Many people report feeling tired following radiotherapy treatment. This could be for a number of reasons related to your body’s natural healing processes but also because you are in pain, feel anxious or have to travel for treatment. Levels of tiredness can increase during radiotherapy treatment so it is important to look after yourself by eating and drinking healthily, resting as necessary and accepting help when it is offered.

How long does tiredness persist after radiotherapy?

Tiredness can continue for a few weeks after radiotherapy because your body is still adjusting to the treatment and still healing any damaged tissues.

Any radiation used during external beam radiotherapy will pass instantly through your body and not leave you radioactive. This means that your friends and family will be safe spending time with you.
