Proton (proton-beam) therapy is a type of external radiation therapy that uses protons instead of X-rays to deliver dose to a tumor, per the U.S. National Cancer Institute's Dictionary of Cancer Terms. It requires a dedicated proton facility, which is far rarer and more capital-intensive than standard photon radiotherapy, so availability in any given country, including Turkey, is limited and hospital-specific; confirm directly with a named center whether it operates a proton unit rather than relying on a facilitator's claim. OncologyIstanbul does not publish a proton-therapy price, because no verified partner-hospital quote exists, and conventional IMRT/VMAT or stereotactic radiosurgery is the widely available option most treatment plans use — whether proton therapy would change anything for your case is a question for the tumor board. Your free tumor-board second opinion can tell you whether proton therapy is relevant to your plan. This is general information, not medical advice.
