radiation therapy
External beam radiation therapy (also known as external beam teletherapy, or long-distance therapy) being delivered using a machine known as a linear accelerator.
In remote brachytherapy, radioactive sources are delivered to a tumour through tubes and subsequently withdrawn. While general brachytherapy involves implanting encapsulated radioactive sources directly into tissue or body cavities using catheters or needles, the remote technique specifically utilizes these tubes to transport the source to the target site and then remove it after the treatment is complete. This method allows for the precise delivery of high radiation doses to the tumor while minimizing exposure to surrounding healthy tissue.12
