癌症早期症狀多不明顯,篩檢能夠早期發現癌症或其癌前病變,經早期診斷治療後,除了可以大幅降低死亡率外,也能阻止癌前病變細胞發展為癌症。
參加臨床實驗的病患有機會得到其所參與實驗的新療法的幫助,但是新的治療方式並不保證會有良好的結果,新療法也可能有未知的風險,嚴重的話甚至會導致死亡。但如果新療法成功的話,接受實驗的病人可能會最先受益。臨床實驗在美國有相當嚴格的進行規範,無論是在人選的選擇以及藥物劑量都有標準操作原則。以避免研究者為了加速研發新藥物,不顧病患的權益,貿然在人體上進行高風險的新療法測試。實際上有許多例子也顯示,即使是通過嚴格標準篩選出可進入臨床實驗階段的抗癌藥物,在臨床上的結果並未如預期的有效。這樣的結果也反映癌症的多原性以及人體系統的複雜度,我們在抗癌藥物的研發上仍有漫長的路途要走。
Predicting shorter- or extensive-expression survival is dependent upon a lot of aspects. The main would be the most cancers sort and also the affected individual's age and Over-all overall health. Those people who are frail with other health conditions have reduce survival fees than normally healthy persons. Centenarians are unlikely to outlive for 5 years even though treatment is thriving.

会破坏正常组织;可有手术并发症,可致畸形、影响正常功能,甚至危及生命;已有转移者,不能完全治愈;重要器官无法彻底切除。
A considerable proportion of cancers are adenocarcinomas, with common histopathology capabilities revealed, Even though they differ considerably 癌症 from situation to situation. Cancers are categorized by the type of mobile which the tumor cells resemble and is thus presumed to generally be the origin of the tumor. These types consist of:
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)
