Internal Radiation Therapy

Submit Abstract Register Now

Internal radiation is also called brachytherapy. A radioactive implant is put inside the body in or near the tumor. Internal radiation therapy (brachytherapy) allows a higher dose of radiation in a smaller area than might be possible with external radiation treatment. It uses a radiation source that’s usually sealed in a small holder called an implant. Different types of implants may be called pellets, seeds, ribbons, wires, needles, capsules, balloons, or tubes.
