What is brachytherapy?
In brachytherapy the radioactive source is either placed very close to the tumor or directly into the tumor. In this approach the rays only have a short distance to travel in the body. The Greek word for “short” is brachys, and this is where the word “brachytherapy” comes from. Radioactive substances are used as the source of radiation for internal radiotherapy.
The aim of using radiotherapy in malignant tumors is to destroy the cancer cells, while at the same time trying to limit the damage to the surrounding healthy tissue. This is one of the main goals of brachytherapy, in which radioactive materials are implanted directly into or near the tumor during a small operation. Unlike external radiotherapy, radiation can reach the tumor directly, thereby minimizing the damage done to healthy tissue. Doctors are still trying out different types of radiotherapy in order to find out which approach is suitable for different people and situations.
