放疗与化疗有什么区别 房永宏 山西省肿瘤医院

放疗与化疗有什么区别 房永宏 山西省肿瘤医院 放疗和化疗是两种完全不同的治疗方法。放疗是用放射线杀死局部的癌细胞的疗法，它属于局部治疗，放射线本身具有能量，称为辐射能，辐射在自然环境中可以诱发癌变，而在放疗中辐射则可作为杀灭癌细胞的一种有效手段，通过射线与癌细胞间能量的传递引起癌细胞结构和细胞活性的改变，最终杀死癌细胞。它的优点，此法对癌症早期效果较好，那么缺点是副作用相对大，无法局部根治的，主要是对局部治疗。那么放疗以后假如这个部位要做手术一般要慎重，放射剂量不要给的太大，给足剂量，做手术以后伤口不容易愈合。化疗一般是中晚期癌症或者恶性肿瘤病人的首选治疗方法，治疗的原理就是向患者体内注入化学药物，通过影响细胞的合成，杀死肿瘤细胞，抑制肿瘤细胞的生长繁殖和促进肿瘤细胞的分化，它的化疗的毒副作用也是比较大的，可以有脱发、骨髓抑制、恶心、呕吐等。 What's the difference between radiotherapy and chemotherapy Radiotherapy and chemotherapy are two completely different treatment methods. Radiotherapy is the treatment of killing local cancer cells with radiation, It belongs to local treatment, The radiation itself has energy, It's called radiant energy, Radiation can induce cancer in the natural environment, Radiation can be used as an effective way to kill cancer cells in radiotherapy, Through the energy transfer between radiation and cancer cells, the structure and activity of cancer cells are changed, Eventually kill the cancer cells. Its advantages, This method has a good effect on the early stage of cancer, The disadvantage is that the side effects are relatively large, If it can't be cured locally, Mainly for local treatment. After radiotherapy, if this part needs to be operated on, it should be cautious, Don't give too much radiation, Give enough dose, The wound doesn't heal easily after the operation. Chemotherapy is generally the first choice for patients with advanced cancer or cancer, The principle of treatment is to inject chemicals into patients, By influencing cell synthesis, Kill tumor cells, Inhibit the growth and proliferation of tumor cells and promote the differentiation of tumor cells, Its side effects of chemotherapy are also relatively large, It can have alopecia, myelosuppression, nausea, vomiting, etc.
