Radiotherapy is only occasionally used to treat gestational trophoblastic disease that has spread to the brain.

Radiotherapy uses x-rays to kill cancer cells or injure them so they cannot multiply. It is usually given in a hospital radiotherapy department. The treatment is painless when it is given.

Side effects of radiotherapy

The side effects of radiotherapy vary depending on the strength of the radiotherapy dose and the length of your treatment. The most common effects occur during or soon after treatment, however some women experience long-term side effects.

The Cancer Council booklet, Understanding Radiotherapy, has more information about radiotherapy. It is available free online or by calling the Cancer Council Helpline (13 11 20).
