Radiotherapy for anal cancer
Radiotherapy uses high energy x-rays to destroy cancer cells. It is a common treatment for anal cancer.
You usually have radiotherapy combined with chemotherapy (chemoradiotherapy) as your main treatment. But you might also have radiotherapy on its own for anal cancer that has spread elsewhere in the body (advanced anal cancer).
Having radiotherapy for anal cancer

Side effects of radiotherapy for anal cancer
Radiotherapy for anal cancer can cause side effects. These may last a few months after treatment and include frequent loose poo (diarrhoea) and sore skin around the anus.
Long term side effects of anal cancer radiotherapy
Radiotherapy for anal cancer can cause long term side effects. Some can start months or years after treatment. They are rare but your doctor or specialist nurse can help you manage them.
