Pediatric Patients: Children are more susceptible to radiation damage, making the precision of particle therapy advantageous. Head and Neck Cancers: Tumors in these areas are often close to critical structures, where precision is paramount. Spinal Tumors: The spinal cord is highly sensitive to radiation, making particle therapy a safer option. Radioresistant Tumors: Tumors that do not respond well to conventional radiation therapy can often be effectively treated with particle therapy.
