Radiation Therapy

Radiotherapy treats cancer by using high-enery rays which destroy the cancer cells while doing as little harm as possible to normal cells. Radiotherapy for cancer of the cervix can be given externally or internally, and is often administered as a combination of the two.

External Radiotherapy is given by directing high-energy rays over the area of the cancer. The type and length of treatment will depend on the size and location of the cancer, lasting up to a few weeks.

Internal (interacavity) Radiotherapy Intracavity radiotherapy is sometimes called brachtherapy. The procedure involves inserting a radioactive metal applicator into the cervix under an anaesthetic. Open tubes are placed close to the cervix, into which a machine that is called a selectron feeds radioactive sources (small radioactive metal balls). They are generally in place for one to two days. Sometimes, an implant containing a higher dose of radioactivity (microselectron) is used and this is only in place for a few hours, or sometimes a few minutes. These shorter treatments may need to be repeated several times, a few days apart, on an outpatient basis.
