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 perfectly-regarded example of this is the Philadelphia chromosome, or translocation of chromosomes 9 and 22, which happens in chronic myelogenous leukemia and ends in manufacture of the BCR-abl fusion protein, an oncogenic tyrosine kinase.

Surgical procedure is the key means of cure for some isolated, strong cancers and should Participate in a job in palliation and prolongation of survival. It is often a very important Portion of the definitive prognosis and staging of tumors, as biopsies are often expected.

Cancers are caused by a number of mutations. Every single mutation alters the habits of your mobile fairly. Cancer is essentially a condition of tissue expansion regulation. For a normal cell to transform right into a most cancers mobile, the genes that regulate cell expansion and differentiation need to be altered.[ninety nine]

以放疗为主要手段来杀灭瘤细胞，达到治愈的目的。适用于鼻咽癌、头颈部癌症、前列腺癌、宫颈癌、肛管癌、肺癌、食管癌、恶性淋巴瘤、皮肤鳞癌、骨巨细胞瘤等。

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。

The true secret innovation listed here lies in the usage of protein cage nanoparticle-primarily based programs. These programs are engineered to carry alerts that bring in NK cells 癌症 directly to the tumor, beating on the list of important issues in cancer immunotherapy: making sure that the immune cells find and assault only the cancer cells with no harming healthful tissue.

雖然癌症症狀的治療並不被視為是癌症的治療方法，但對於癌症病患的生活品質有重要的幫助，也能用來評估病患是否能進一步接受其他治療。儘管所有醫師都能夠使用藥物來減輕或抑制疼痛、噁心、嘔吐、腹瀉、出血及其他癌症患者常見的症狀，舒緩治療的進一步發展對於有這一方面的需求的病患仍然是相當重要的。

免疫療法是利用人體內的免疫機制來對抗腫瘤細胞。已經有許多對抗癌症的免疫療法在研究中。目前較有進展的就是癌症疫苗療法和單株抗體療法，而免疫細胞療法則是最近這幾年最新發展的治療技術。

[238] People today from Asian and South American nations also have a tendency to want a slower, much less candid approach to disclosure than is idealized in The usa and Western Europe, plus they believe that often It could be preferable never to be told about a most cancers diagnosis.[238] On the whole, disclosure with the diagnosis is more widespread than it had been during the twentieth century, but comprehensive disclosure of your prognosis just isn't made available to quite a few clients worldwide.[238]

The Dutch professor Francois de la Boe Sylvius, a follower of Descartes, believed that all sickness was the result of chemical procedures and that acidic lymph fluid was the cause of most cancers. His modern Nicolaes Tulp thought that cancer was a poison that gradually spreads and concluded that it was contagious.[230]

準確的癌症分期與診斷對於癌症的治療相當重要，癌症治療的原則是先確立治療目標，主要目標則可分為治癒癌症、延長生命、減輕痛苦及安寧療護四大類，常見的治療方式有以下幾項。
