癌症篩檢，是希望在一般大眾身上提早找出潛在未發現與早期無症狀的癌症。所進行的測試必須適合廣大民眾能夠負擔，並且安全，無侵入性而且不易有假陽性結果產生。一旦發現癌症的跡象，更精確的後續檢驗，或使用侵入性手術取得組織切片以確定篩檢結果則是必要的。

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。
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。
