癌症篩檢的爭議在於檢驗是否的確能夠延長生命，由於癌症的治療方法多半具有侵入性及對身體造成很大負擔，因為早期發現而進行治療反而不一定比完全不治療好。例如，在進行前列腺癌篩檢時，攝護腺抗原血液檢驗可偵測到極微小的腫瘤，但是或許終其一生，這樣的腫瘤並不會成為危及生命的問題。只是一旦經篩檢發現，一般都會進行進一步的檢驗及診療。因此就有可能發生過度診斷（英语：overdiagnosis）的問題，而將病患放入不必要的併發症的風險中，如手術或放射治療的副作用與感染。用於確定診斷前列腺癌所做的前列腺組織切片可能引起的副作用，包括出血和感染。前列腺癌的治療則可能導致尿失禁、勃起功能障礙。同樣地，對於乳癌的篩檢上，近來也有批評認為在一些國家所進行的乳房篩檢計畫所引起問題遠超過所解決的。因為在一般婦女身上做篩檢，產生許多因為陽性或假陽性結果而需要做更精確檢驗的婦女，造成醫療資源的大量浪費，也帶給假陽性者的沉重心理負擔。而這樣大規模的檢驗，最後往往只是找出幾個早期乳癌患者，所耗費的社會成本是值得討論的。
Cancers are generally named using -carcinoma, -sarcoma or -blastoma as a suffix, While using the Latin or Greek word to the organ or tissue of origin as the basis. By way of example, cancers in the liver parenchyma arising from malignant epithelial cells is called hepatocarcinoma, although a malignancy arising from primitive liver precursor cells known as a hepatoblastoma as well as a most cancers arising from fat cells is named a liposarcoma.
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）
The central role of DNA problems and epigenetic defects in DNA repair genes in carcinogenesis The classical view of cancer can be a set of ailments driven by progressive genetic abnormalities that include mutations in tumor-suppressor genes and oncogenes, and in chromosomal abnormalities. A role for epigenetic alterations was determined during the early twenty first century.[103]

good when I start out the sport, enter the game and over the map it states this: NFO: 1 scripts are running but are using the 癌症 v2 API!

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。
Local indications may well arise due to mass in the tumor or its ulceration. By way of example, mass effects from lung cancer can block the bronchus causing cough or pneumonia; esophageal cancer may cause narrowing of your esophagus, rendering it tricky or painful to swallow; and colorectal most cancers may well result in narrowing or blockages from the bowel, influencing bowel practices. Masses in breasts or testicles may make observable lumps.
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：
烟草使用、酒精消费、不健康饮食、缺乏身体活动和空气污染是癌症（以及其他非传染性疾病）的危险因素。
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。
The medical professional John Hill described tobacco sniffing as the cause of nose cancer in 1761.[229] This was followed by the report in 1775 by British surgeon Percivall Pott that chimney sweeps' carcinoma, a most cancers in the scrotum, was a typical sickness between chimney sweeps.
Procedure is normally similar to for non-Expecting Women of all ages. Having said that, radiation and radioactive drugs are Commonly prevented all through pregnancy, particularly when the fetal dose could exceed one hundred cGy. Occasionally, some or all therapies are postponed until eventually after start If your cancer is diagnosed late in the pregnancy.
