在本项研究中，团队利用给癌细胞高效输送抗癌剂的抗体-药物复合体技术，研发出能选择性聚集到癌组织的活性氧探针。这种探针用绿色和红色两种荧光分子修饰能和癌细胞特有表面抗原结合的抗体，观察两种荧光的强度就能评估出癌细胞及周围过氧化氢（活性氧的一种）的量。借助这种探针，研究人员发现癌组织内存在过氧化氢高浓度积聚的热点区域。而在此热点区域肿瘤出芽现象高频发生。肿瘤出芽指癌细胞从原发肿瘤脱离，进入肿瘤基质的现象。肿瘤出芽指示着癌症转移的初期阶段。研究人员认为，从机制上说，暴露于过氧化氢的癌细胞通过部分激活上皮间质转化，从过氧化氢高浓度热点区域逃离。这种逃逸机制在正常上皮细胞中不存在，但在大多数癌症中普遍存在。它揭示了癌细胞内在的应激防御程序。研究团队认为，癌细胞为了躲避对自己有害的活性氧，迈出了转移的第一步。

A mutation in the mistake-correcting equipment of a mobile may well result in that mobile and its kids to build up mistakes extra speedily.
癌症有超過一百個種類，一般可依據癌細胞原發部位來分類，例如肺癌、乳癌等；另外能根據不同組織或細胞做以下分類：
Cancers are because of a number of mutations. Each individual mutation alters the actions of your mobile rather. Most cancers is basically a condition of tissue development regulation. For a normal mobile to remodel into a most cancers mobile, the genes that regulate mobile expansion and differentiation need to be altered.[99]
乙肝病毒、丙肝病毒和某些类型的人乳头瘤病毒可分别增加罹患肝癌和宫颈癌的危险。艾滋病毒感染会使患宫颈癌的风险增加六倍，并还会大幅增加患其他癌症，如卡波西肉瘤的风险。
疼痛：肿瘤因生长、转移等破坏、侵犯局部组织或神经，出现各种不同性质、程度的疼痛感，夜间痛较为明显。

放射治疗即常说的放疗，根据其治疗方式及适应证可分为根治性放疗、姑息性 放疗和联合治疗，具体内容可参考百度百科及百度药典，在此不过多介绍。但需要 注意，放疗并不一定能完全治疗癌症，且在治疗过程中会出现诸多不良反应，如 乏力、恶心、厌食、皮肤痒肿、口咽疼痛、局部毛发脱落、神经损伤、心肺功能 异常（如干咳、气喘等）、胃肠功能紊乱（如恶心、呕吐、体重下降等）等。
Engraving with two sights of a Dutch woman who had a tumor faraway from her neck in 癌症 1689 Most cancers has existed for all of human heritage.[226] The earliest published report about most cancers is from c. 1600 BC from the Egyptian Edwin Smith Papyrus and describes breast cancer.[226] Hippocrates (c. 460 BC – c. 370 BC) described a number of sorts of cancer, referring to them with the Greek term καρκίνος karkinos (crab or crayfish).[226] This title originates from the looks with the Slice surface area of the good malignant tumor, with "the veins stretched on all sides given that the animal the crab has its feet, whence it derives its name".
不斷增生的癌細胞撐破腫瘤，癌細胞因而擴散至腫瘤周遭的組織及鄰近的淋巴結甚至更遠處。此時癌細胞流竄於原始病灶附近，必需借助循環全身的化學治療藥物治療。
与其他方法一起，可延缓病变进展、改善症状，对肛管癌、卵巢癌、乳腺癌、膀胱癌、喉癌、骨肉瘤、直肠癌、胃癌、基底细胞癌等疗效确切，对食管癌、非小细胞肺癌、鼻咽癌、恶性间皮瘤、子宫内膜癌、胰腺癌、前列腺癌等可能有价值。
