The smart Trick of 癌症 That Nobody is Discussing
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：而根據癌症發展的程度，又可分為零、一、二、三、四期等，及早期與晚期，通常零到一期算是早期，但在不同癌症中每期的定義和治療方法都有所不同，確實的分期仍應參考美國癌症聯合委員會的定義。
姑息治疗的目的不是治愈癌症，而是缓解癌症引起的症状和痛苦，并提高患者及其家人的生活质量。姑息治疗可帮助患者生活得更舒适。在癌症晚期患者比例较高且治愈几率很小的地方，尤其需要这种疗法。
註解：癌細胞將於所到之處繼續失控的繁殖。舉例：若肺癌細胞轉移到肝臟，則肝臟將出現不斷增生的肺部細胞（不具肺功能），且此細胞具有入侵正常肝臟細胞的能力，導致肝功能不斷降低；反之，不具入侵能力但失控繁殖的細胞，稱為良性腫瘤。
對於癌症高風險群，例如有家族病史，或是環境汙染（例如輻射屋居民）的人進行基因檢測，可做較深入仔細的檢查分析，服用預防藥物。確定有癌症相關基因突變的人，可藉由預防性的手術，降低癌症機會。
People that endure most cancers establish a 2nd primary cancer at about two times the rate of those never ever diagnosed.[208] The enhanced hazard is thought being a result of the random probability of producing any cancer, the chance of surviving the main cancer, the identical threat elements that created the first most cancers, unwanted Uncomfortable side effects of treating the primary most cancers (specifically radiation therapy), and better compliance with screening.[208]
現代人工作忙碌，飲食習慣差，多為外食、重口味並常延遲用餐，加上生活壓力大、熬夜、作息不穩定，以及長期久坐、缺乏運動等，這些不良生活習慣都會增加罹癌風險。
This is predicated on the blamers' belief that the world is essentially just and so any unsafe sickness, like most cancers, need to be a form of punishment for negative options, because in a very just entire world, poor matters would not materialize to very good individuals.[246]
出生后发生的基因突变。大多数基因突变会在您出生后发生，并且不会被遗传。有多种因素会导致基因突变，例如抽烟、辐射、病毒、致癌化学物质（致癌物）、肥胖症、激素、慢性发炎和缺乏运动。

Which therapies are employed is determined by the type, locale and grade of the most cancers plus the affected person's health and Choices. 癌症 The remedy intent might or might not be curative.[citation essential]
It had been found that delivering put together cytotoxic medicines is a lot better than only one drug, a procedure named The mix therapy, that has a benefit within the stats of survival and reaction into the tumor and within the progress in the ailment.
用醫學影像技術檢測癌症，也遭遇類似問題。這些醫學影像檢測技術都是成本相當高且耗費時間。由於偵測的靈敏度極高，常發現細胞病變（英语：incidentaloma），這樣的腫瘤也可以被認為惡性，而進行具有潛在危險性的治療方法。
The conclusions that result depend upon most cancers's type and placement. Several signs and symptoms are distinct. Lots of often arise in people who produce other conditions. Most cancers may be tough to diagnose and might be viewed as a "great imitator".[33]
