然而,肿瘤细胞致死剂量与正常组织耐受剂量的差别一般不是太大,当放射剂量

However, the difference between the lethal dose of tumor cells and the tolerated dose of normal tissues is generally not too large. When the radiation dose reaches a certain amount, although the dose can kill all tumor cells, it often exceeds the tolerated dose of normal tissues, especially The size of the so-called "parallel" tissue tolerable dose also depends on the extent of the irradiated tissue, the larger the extent, the smaller the ability of the tissue to withstand radiation.
