Treatment
Your radiotherapy treatment plan is individual to you. Your radiotherapy team carefully work out how much radiation you need and exactly where you need it.
You have external radiotherapy in a hospital radiotherapy department. You usually have it as an outpatient each weekday over 3 to 6 weeks.
Stereotactic radiotherapy is a type of external radiotherapy. Some people may have a very high dose of stereotactic radiotherapy over one treatment. This is called stereotactic radiosurgery.
Radiotherapy to the brain and spinal cord can cause side effects. These include tiredness and feeling sick.
