Pancreatic
The pancreas is located in the mid-abdominal area and is surrounded by several critical organs including the liver, kidneys, stomach and the small and large intestines. Due to this critical location and the radiation sensitivities of these organs, it is imperative to keep radiation doses to these organs limited to prevent nausea and vomiting, and to preserve organ function. For these reasons, proton therapy is highly indicated in order to deliver a curative dose to the tumor and limit dose to these surrounding organs.
