The cost of radioactive particle implantation currently includes the following points: 1. The cost of particles is generally $420/g, but the number of particles is related to the volume of tumor. The larger the tumor volume is, the more the number of particles to be implanted. Therefore, the doctor will make a correct calculation according to the preoperative radioactive particle treatment planning system, i.e. TPS planning system, to accurately calculate the number of particles. The higher the number of particles, the higher the cost incurred may be; 2. The surgical cost related to particle implantation. This includes the surgical cost of particle implantation, CT-guided or ultrasound-guided surveillance costs. However, all of the above are covered by medical insurance reimbursement. Therefore, the patient’s treatment cost will not incur huge treatment cost after being reimbursed by medical insurance. The patient is equivalent to a normal hospitalization, which is affordable for an average family.
