最近放射线疗法的重要性与日俱增。这种方法对于内脏器官及身体的损伤少,进行社会恢复也容易。在美国全部癌患者的60％日本40％的人都接受了放射线疗法。放射线医疗研究的大型设备,其特点是使用比最轻的氢原子核重的重粒子(氦、碳、氖等的原子核),根据预测,用这些重粒子进行辐射手术的直肠癌、肺癌,大多数不需要再进行外科手术。在目前的放射线治疗的条件下有半数在局部地方复发的头颈部癌,用重粒力射线治疗60——80％能稳定下来。对食道癌的治愈率也大幅度提高。 The importance of radiotherapy is increasing day by day. This method has less damage to the internal organs and the body, and it is easy to perform social recovery. 60% of all cancer patients in the United States, 40% of people in Japan have received radiation therapy. The large-scale medical equipment for radiation therapy research is characterized by the use of heavier particles (helium, carbon, and helium, etc.) that are heavier than the lightest hydrogen atoms. According to predictions, these heavy particles are used for radiation surgery for rectal cancer, lung cancer, and most No further surgery is required. In the current radiation therapy conditions, half of the head and neck cancers that have recurred in local areas are treated with heavy granule rays and 60 to 80% can be stabilized. The cure rate for esophageal cancer has also increased significantly.
