Dr. Shah's clinical team compared a RapidArc treatment plan with one for conventional IMRT and found that the RapidArc plan spared more of Kelver's salivary glands and the rest of his oral cavity. "Prior forms of radiation therapy might have severely compromised his salivary function, which can lead to a permanent and severe dry mouth condition that would have affected his eating, digestion, taste, and dental health," Dr. Shah said.

And with treatments being completed so quickly, these two can get in and out of the office faster and spend more quality time together."
Another patient, Raymond Kelly, is a 72-year-old man with stage 3 lung
cancer that has spread to his lymph nodes on both sides. "With earlier
forms of radiation therapy, once a tumor spreads to this degree, you have
to limit the dose because of all the healthy lung tissue you would
otherwise damage during treatment," Dr. Shah explained. "The RapidArc
