Radiotherapy for skin cancer
Radiotherapy uses high-energy x-rays to destroy the cancer cells, while doing as little harm as possible to normal cells. It may be used to treat some skin cancers.
Radiotherapy uses x-rays to destroy the cancer cells, while doing as little harm as possible to normal cells.
It is sometimes used instead of surgery to treat basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) of the skin. You usually have external beam radiotherapy for skin cancer. Occasionally, a type of internal radiotherapy called brachytherapy might be used.
Radiotherapy is particularly useful if surgery might be too difficult or affect your appearance. For example, it may be used for skin cancer that:
- affect parts of the face, such as the nose
- affect large areas
- are deep in the skin.
Radiotherapy is not recommended for young people with skin cancer. This is because it can cause skin changes that may become more noticeable over time.
Radiotherapy is occasionally used when a non-melanoma skin cancer has spread to other places. This can include lymph nodes or an organ such as, the lungs. Sometimes it may be given after surgery if there is a risk that not all the cancer cells have been removed.
You have radiotherapy in the hospital outpatient department. Depending on the type and size of skin cancer, you may only have 1 treatment session. But usually several sessions are needed. You may have radiotherapy each day, 5 days of the week, for 1 or more weeks. Your doctor will discuss your treatment plan with you.
If you are having brachytherapy your doctor will explain more about it.

Effects on the skin
At first, this new skin will look pinker than the skin around it. But it should gradually fade to look more like the skin around it. If you have fair skin, the treated area may become slightly paler. If you have dark skin, the area may get darker or paler. We have more information about radiotherapy skin reactions.

The language we use
We want everyone affected by cancer to feel our information is written for them.
We try to make sure our information is as clear as possible. We use plain English, avoid jargon, explain any medical words, use illustrations to explain text, and make sure important points are highlighted clearly.
We use gender-inclusive language and talk to our readers as ‘you’ so that everyone feels included. Where clinically necessary we use the terms ‘men’ and ‘women’ or ‘male’ and ‘female’. For example, we do so when talking about parts of the body or mentioning statistics or research about who is affected. Our aims are for our information to be as clear and relevant as possible for everyone.
