Overview
3D conformal radiation therapy uses CT scans to build a three-dimensional picture of the tumour and nearby organs. Several radiation beams are shaped to fit the tumour, so it receives a high dose while surrounding healthy tissue is spared as much as possible.
Why it is done
- To destroy cancer cells or stop them growing
- After surgery, to lower the chance of the cancer coming back
- Together with chemotherapy for some cancers
- To relieve pain or other symptoms from advanced cancer
Before treatment
A planning CT scan is done in the treatment position. Small skin marks may be made so you can be positioned the same way each day. The team then calculates the beam angles and doses.
During treatment
Treatment is usually given once a day, five days a week, for several weeks. Each session takes a few minutes. It is painless, and you will not be radioactive afterwards.
Risks
Side effects depend on the area treated and may include tiredness, skin redness, and temporary irritation of nearby organs such as the bowel or bladder. Your team will explain the specific risks for you.
At KIH
KIH's haematology and oncology team can assess you, coordinate your cancer care and guide you to a centre offering radiotherapy when it is needed.
