IGRT  We use image guided radiation therapy (IGRT), one of the most cutting-edge innovations in cancer technology available. Tumors can move, because of breathing and other movement in the body. IGRT allows our doctors to locate and track the tumor at the time of treatment. With this technology, we can deliver precise radiation treatment to tumors that shift as a result of breathing and movement of the bladder and bowels. This also allows our radiation oncologists to make technical adjustments when a tumor moves outside of the planned treatment range. As a result, the radiation treatment is targeted to the tumor as much as possible, helping to limit radiation exposure to healthy tissue and reduce common radiation side effects.
