19 de mar. de 2024 · Radiation therapy, the use of ionizing radiation (high-energy radiation that displaces electrons from atoms and molecules) to destroy cancer cells. In addition to treating cancer, radiation oncologists may also use ionizing radiation to treat benign tumors that are unable to be removed by surgery.
Há 5 dias · Proton therapy is a type of external beam radiotherapy, and shares risks and side effects of other forms of radiation therapy. The dose outside of the treatment region can be significantly less for deep-tissue tumors than X-ray therapy, because proton therapy takes full advantage of the Bragg peak.

8 de mar. de 2024 · Radiation Therapy (RT) is a specialized cancer treatment using radioactive rays from a Linear Accelerator (LINAC) to damage specific malignant cells. High-energy waves like x-rays, gamma rays, electron beams, or protons are accelerated in the LINAC to destroy cancer cells.
6 de mar. de 2024 · Nuclear medicine, medical specialty that involves the use of radioactive isotopes in the diagnosis and treatment of disease. Nuclear medicine began only after the discovery by Enrico Fermi in 1935 that stable elements could be made radioactive by bombarding them with neutrons.
