Radiotherapy uses high energy waves similar to x-rays to kill cancer cells. It's often the first choice of treatment for laryngeal cancer.
The radiotherapy team plans your external beam radiotherapy before you start treatment. This means working out the dose of radiotherapy you need and exactly where you need it.
You might have radiotherapy on its own as your main treatment, or combined with other treatments such as surgery, chemotherapy or targeted cancer drugs.
External beam radiotherapy directs radiotherapy beams at the cancer from a machine. You have it in the hospital radiotherapy department.
Side effects tend to start a week after the radiotherapy begins. They can include feeling tired, sore skin, a sore throat and difficulty swallowing.
