理論上，若是以手術完全移除腫瘤細胞，癌症是可以被治癒的。但並非總是如此簡單，外科手術通常無法切除已經轉移到其他部位的癌細胞。使用外科手術治療癌症的例子包括以乳房切除术治療乳癌或是進行前列腺切除術（英语：prostatectomy）治療前列腺癌。手術的目的在於移除腫瘤細胞或是整個器官，雖然將主要的腫瘤經外科手術切除，但仍有些潛伏在腫瘤所生長的器官週遭的單一腫瘤細胞是無法被察覺的。隨著時間過去，又會重新生長成一個新的腫瘤，稱為癌症復發。為此，手術切除下的腫瘤需要經病理學家的檢視，以確定切下的腫瘤週遭都是正常組織，減少腫瘤切除不完全的機會。
中医治疗作为我国的传统特色，我们也专门总结了一篇中医治疗方法(详见，放链接)。 中医主要用于治疗晚期癌症，包括肺癌、胃癌、肝癌、结直肠癌、乳腺癌、淋巴瘤、 食管癌、鼻咽癌等，有时还可联合化疗或放疗，以缓解不良反应，提高疗效。同时， 中医在术后恢复方面也有较好的应用效果。
A mutation in the error-correcting machinery of a mobile might result in that cell and its children to accumulate problems additional rapidly.
Medical procedures is the first approach to remedy for some isolated, good cancers and will play a role in palliation and prolongation of survival. It is often an important Portion of the definitive diagnosis and staging of tumors, as biopsies usually are demanded.
Carcinoma: Cancers derived from epithelial cells. This team incorporates many of the most common cancers and include things like nearly all Individuals during the breast, prostate, lung, pancreas and colon. A large number of are from the adenocarcinoma sort, which means that the most cancers has gland-like differentiation.
物理致癌物，例如紫外线和电离辐射；而异物刺激、创伤、慢性炎症等会促进恶变进程。
化学致癌物，例如石棉、烟草烟雾成分、酒精、黄曲霉毒素（一种食品污染物）和砷（一种饮水污染物）；
多數癌症是自發性的（英语：sporadic），但是有些癌症還是與遺傳有關，通常遺傳到缺陷的腫瘤抑制基因時會有較顯著的影響和症狀。舉例而言：
An extra mutation within an oncogene could possibly induce the mobile to breed far more swiftly plus much more often than its normal counterparts.
Woodland Park Zoo recognizes that these are definitely the lands in the Tribal signatories with the Treaty of Level Elliott. We accept their stewardship of the put continues to this day and that it is our duty to affix them to revive the relationship Along with the residing environment about us.
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。
免疫細胞療法是最近這幾年開發的最新技術，原理是直接將大量未分化的樹狀細胞投入腫瘤中或腫瘤周邊的血管中，能迅速且大量的強化樹狀細胞辨識特定癌細胞的能力，使樹狀細胞可在短時間內幫助輔助型T細胞（helper T mobile）快速誘導出大量細胞毒殺性T淋巴球（CTL），以攻擊特定癌細胞。目前此項研究已在日本進入臨床試驗階段。
In The usa, most cancers is incorporated as being a secured situation because of the Equal Employment Prospect Fee (EEOC), primarily due to the probable for most cancers having discriminating results on personnel.[253] Discrimination in the workplace could take place if an employer holds a Phony perception that anyone with most cancers 癌症 just isn't capable of undertaking a job appropriately, and should check with for more sick go away than other employees.
