How does gamma radiation work
WebRadiation works by making small breaks in the DNA inside cells. These breaks keep cancer cells from growing and dividing and cause them to die. Nearby normal cells can also be affected by radiation, but most recover and go back to working the way they should. WebHow does radiotherapy work? Radiotherapy uses radiation — rays of very powerful energy — to kill cancer cells in a specific area. It is an effective treatment for many cancers, but certain cancers respond better to radiation, for example, cancers of the head and neck. Like other cancer treatments, radiotherapy can be used in different ways:
