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。

相較於遺傳性的基因缺陷,生活方式對於癌症的發生並沒有決定性的影響,這是很重要的一個觀念,現今所謂的危險因子,雖然都是經過流行病學的嚴謹分析而得出的結論,但是科學的結論必須要在嚴格的條件控制之下才會成立。雖然抽菸的確會提高罹患肺癌的機率,但直到目前為止,醫學上仍舊無法精確的定義出抽菸的量,或是幾歲開始抽,一定會引起肺癌。每個人在基因上的不同,使得每個人對不同物質的反應都不相同。所以並沒有所謂絕對健康的生活方式,坊間許多生機飲食和眾多號稱防癌的健康食品,所能得到的效果並不大。不需要杞人憂天的飲食及生活,即使是癌症病患,只要保持正常生活,適當補充養分即可。但是有些高危險因子是所有人都應該要小心避免的,例如抽菸、喝酒、進食快餐和嚼檳榔等。

In non-individuals, a couple of kinds of transmissible most cancers have also been described, whereby the cancer spreads in between animals by transmission of your tumor cells by themselves.
In The us and Another cultures, most cancers is viewed as a ailment that has to be "fought" to end the "civil insurrection"; a War on Most cancers was declared within the US. Military metaphors are significantly widespread in descriptions of most cancers's human results, they usually emphasize equally the state on the affected person's health and fitness and the need to choose quick, decisive steps himself 癌症 instead of to hold off, to disregard or to rely totally on Many others.
