Brachytherapy is when a protected radiation source is placed directly within or near the site of the tumor. It is also sometimes referred to as internal radiation therapy.
High-Dose Rate (HDR) Brachytherapy involves placing a protected source of high energy radiation directly within the tumor. Then radioactive material such as plaques, needles, tubes, wires, or small "seeds" made of radio-nuclides are placed over the surface of the tumor, implanted within the tumor, or placed within a body cavity surrounded by the tumor.
Low-Dose Rate (LDR) Brachytherapy on the other hand, places radioactive materials inside the body for extended periods of time.
HDR brachytherapy is usually performed as a short series of outpatient procedures. The high energy radiation used (usually Iridium-192) means that doctors can deliver equivalent doses of radiation in just a few minutes by inserting and then removing the radioactive beads.
Ceylinco Radiation Treatment Unit offers HDR brachytherapy to gynecological cancer patients, and in clinical trials of MammoSite brachytherapy to breast cancer patients. In addition, patients with head and neck cancer, pulmonary cancer, and other local regional tumors can be considered for HDR brachytherapy on an individual basis.
