Radiotherapy explained

Radiotherapy uses high-energy rays to treat cancer.

Radiotherapy can cause side effects. Your radiographer or nurse will give you advice or medicines to help manage them.

A team of specialists are involved in planning and giving your radiotherapy.

During most types of radiotherapy to the brain, head or neck, you wear a mask to help you lie still.

Radiotherapy treats cancer by using high-energy rays to destroy the cancer cells. Using radiotherapy to treat cancer in the pelvis is called pelvic radiotherapy.

External beam radiotherapy is given from a radiotherapy machine outside the body.

Internal radiotherapy is treatment with a radioactive material that is put inside the body to treat cancer.
