Radiation Oncology is a branch of medicine that treats cancer by using high-energy radiation in the form of photons (X-Rays and Gamma Rays) or subatomic particles (electrons or protons). Doctors learned how to use this energy to essentially see inside the body and find disease, as you have probably seen with an x-ray that shows pictures of your teeth or bones. At high doses this radiation can actually be used to treat cancer and other illnesses. Check out the presentation below to learn more about radiation oncology.
