Radiation Oncology

How we can help you

Radiation therapy involves the use of high-energy radiation therapy to control or kill tumour cells. It may be used to cure disease, reduce symptoms such as pain, and/or to prevent disease recurrence. Radiation therapy is a safe, effective and important part of the management of a range of cancers. Radiation can also be used for non-cancerous diseases. It may be given on its own or with other forms of treatment such as chemotherapy or surgery. Like having a routine X-ray, radiation therapy is painless.

Radiation therapy is a localised treatment which means it generally only affects the part of the body requiring treatment. Modern techniques accurately target cancer cells whilst minimising effects on normal healthy tissues.

Radiation therapy is most commonly given in the form of external X-rays generated from a treatment machine (Linear Accelerator). A course of radiotherapy treatment is often delivered over a number of days to weeks.

Radiotherapy treatment can also be delivered internally where small radioactive sources are placed inside the body (Brachytherapy). St George Cancer Care Centre specialises in a comprehensive list of brachytherapy services including prostate, breast, gynaecological, skin, lung and other sites.
