3D Conformal External Beam Radiotherapy is one of the most common forms of external beam radiation therapy. It effectively targets cancer tumours while sparing healthy surrounding tissue.

Intensity-modulated radiation therapy [IMRT] is high precision radiation therapy that delivers high dose, modulated radiation beams to cancerous tumours, while limiting impact on healthy surrounding tissue.

Volumetric modulated arc therapy [VMAT] involves the use of external radiation therapy beams being directed in a series of arcs or angles to allow for greater access to tumour. VMAT allows more difficult tumours, such as ones wrapped around other important structures, to be targeted precisely.

Image-guided radiation therapy [IGRT] is a radiation therapy which utilises advanced imaging equipment and computer software to accurately target tumours. This minimises the impact on surrounding healthy tissues, resulting in fewer potential side effects from treatment.

Stereotactic Radiosurgery is a non-surgical type of radiotherapy that delivers high dose radiation with extreme precision. It is used to treat small, localized tumours, mainly in the brain.

Stereotactic Body Radiotherapy [SBRT] is an advanced technique that delivers high dose radiation with extreme accuracy, used to treat small tumours with a well-defined edge, in the brain, spine or lung.

Paediatric cancers are treated mainly on a protocol basis based on the Children’s Oncology Group (COG) or International Society of Paediatric Oncology (SIOP). Based on the tumor type, our radiation oncologist will discuss with you the radiation treatment plan.

Brachytherapy is a special form of internal radiation therapy where a radioactive source is placed close to or inside the tumour.

Gynaecology brachytherapy is a form of radiation therapy used to treat cervix and endometrial cancer. It is a special form of internal radiation therapy where a radioactive source is placed closed or inside the tumour, to deliver the radiation treatment.
