​Radiation oncology

Radiation therapy or radiotherapy is a type of cancer treatment that uses high-energy radiation to shrink tumors and kill cancer cells. Patients referred for or undergoing radiotherapy treatment are seen by our radiation oncologists in the oncology clinics offering a wide range of services that include:

Brachytherapy is a type of radiotherapy that can be used to treat cervical cancer. In Brachytherapy, the radioactive source is placed as close to the tumour as possible to deliver a very high dose in a localized area. This reduces the risk of unnecessary damage to the healthy tissue and organs close to the tumour. ​

External Beam Radiation Therapy (EBRT)
External radiation (or external beam radiation) is the most common type of radiation therapy used for cancer treatment. A machine is used to aim high-energy rays (or beams) from outside the body into the tumor. Radiation technology allows the very careful delivery of external beam radiation therapy. These machines focus the radiation on the exact location where it needs to be, so that normal tissues are affected as little as possible

Electron Radiotherapy
This type of radiation therapy uses electrons directed at the entire surface of the body. This type of radiation goes into the outer layers of the skin, but does not go deeper into tissues and organs below the skin. ​
