Radiotherapy treats cancer by using high-energy x-rays to destroy cancer cells.
You might have radiotherapy before or after surgery, to treat a secondary cancer, or to shrink or slow the growth of an advanced sarcoma.
The radiotherapy team plan your external beam radiotherapy before you start treatment.
You have radiotherapy in the radiotherapy department of the hospital.
Radiotherapy can cause general side effects as well as more specific ones. Specific side effects depend on where your soft tissue sarcoma is in your body.
