Not known Factual Statements About 癌症

The transformation of a standard cell into cancer is akin to a series reaction caused by Original glitches, which compound into much more intense faults, Each individual progressively making it possible for the mobile to escape additional controls that Restrict standard tissue expansion. This rebellion-like situation can be an unwanted survival with the fittest, in which the driving forces of evolution do the job against your body's structure and enforcement of purchase.

癌症的存活率，會因腫瘤長的位置、大小、數目及癌症的分期而有不同，一般來說，只要早期發現，治癒率就越高；根據統計，發現許多癌症零期（原位癌）的病人，五年存活率幾乎接近百分之百，不過存活率會隨著期別愈晚而降低。（延伸閱讀：原位癌是什麼？剖析癌症進化史）

免疫治疗是当前的研究前沿热点内容，我们也专门总结了一篇免疫治疗方法(详见， 放链接)。其目的主要是通过激发、增强患者本身免疫细胞的免疫功能进行控制、 杀灭肿瘤、以及自身的抗癌过程。其部分方法已开始临床应用，但需要注意多数免疫 治疗还不够成熟，且价格相对高昂，绝大多数仍处于研究阶段。

癌症是全球排在第二位的死亡原因。不过，随着癌症筛查、治疗和预防的改进，多种癌症的生存率有所提高。
