The biggest challenge for radiation oncologists is being able to direct the cancer-killing radiation precisely to the tumor while sparing the surrounding normal tissue from damage. New technology known as "stereotactic radiosurgery" can deliver radiation with millimeter precision -- about the width of a fingernail. New technology offered by Vanderbilt-Ingram Cancer Center in Nashville, Tennessee, can complete treatment in a much shorter amount of time from other systems you may have heard about in the press or advertising.
