Radiation may play several roles in the treatment of chordoma, depending on the stage of the disease. Radiation with beams of charged particles, called particle therapy, is generally recommended for treating chordoma because it can be focused precisely on the tumor. Two types of particles are commonly used: protons and carbon ions. Europe has several centers offering this specialized treatment. For specific details about the treatments offered, referral processes, and eligibility criteria, contact the centers directly or visit their websites.
