Radiotherapy treats cancer by using high-energy x-rays to destroy cancer cells, while doing as little harm as possible to normal cells.
Radiotherapy is occasionally used to treat recurrent melanomas that can’t be removed with surgery or aren’t suitable for other treatments. It may help to shrink large recurrences that are causing discomfort or pain. Your specialist will tell you if radiotherapy is suitable for you.
External radiotherapy doesn’t make you radioactive. It’s perfectly safe for you to be with other people, including children, after your treatment.
