Overview
IMRT shapes and adjusts radiation beams so that the tumour receives a high dose while nearby healthy organs receive less. It is often used for cancers of the head and neck, prostate and brain.
Why it is done
- Tumours close to sensitive organs
- Head and neck, prostate, pelvic and brain cancers
- To reduce side effects such as dry mouth
Before treatment
A planning CT scan is done in the treatment position, sometimes with a mask or mould. Detailed computer planning takes several days.
During treatment
Treatment is usually given daily on weekdays for several weeks. Each session takes about 15 to 20 minutes and is painless.
Risks
Side effects depend on the area treated and may include tiredness, skin changes, dry mouth, bowel or bladder irritation.
