What is intensity modulated radiotherapy?
Intensity-modulated radiotherapy (IMRT). IMRT uses a computer to control the direction, shape, and strength or intensity of the radiation beams.

How does proton beam therapy work?
Proton beam radiation therapy focuses beams of protons instead of x-rays on the cancer. Unlike x-rays, which go through the patient and release radiation both before and after they hit the tumor, protons only travel a certain distance, so the tissues behind the tumor are exposed to very little radiation. Even the tissues in front of the tumor see less radiation than the tumor itself. This means that proton beam radiation can deliver radiation to the cancer while doing less damage to nearby normal tissues. Because there are so many critical structures close by, proton beam radiation can be used to treat certain tumors of the oral cavity or oropharynx. Proton therapy can be a safe option in certain cases when using x-rays is not.
