What do pediatric neurologists do?

What types of rays do neurologists use to heal tumours or cancer in a persons brain?

• do they use gamma rays or x rays to stop the tumour or the cancer in a persons brain. And could you also please explain how the rays the neurologists use stop the tumours or the cancer in a persons brain from growing. How do the rays effect the tumours and the cancer to heal them. Thank you

• Answer:

  Just to understand - gamma rays and x-rays are the same thing, just produced differently. Gamma rays are a product of the the radioactive decay of an element. X-rays are generated in an X-ray tube. Side by side, if you could see them, you would not be able to tell them apart. Cancer treatment is performed using x-ray machines. It allows for the generation of very focused beam of radiation, and a very precise control of level and duration, therefore less collateral damage to surrounding good tissue. Often you get a tattoo on your body to mark the spot for repeated therapy sessions. The direction of gammas from radioactive decay is not controllable.
