惡性腫瘤的命名通常使用其發生器官的拉丁文或希臘文作為字首,上述類別則作為字根來命名。對於常見的癌症,有時會使用英文的器官名來代替希臘或拉丁文名。例如,最普遍的乳癌類型即名為ductal carcinoma on the breast或者是mammary ductal carcinoma。而在中文领域,则分为两种情况。如果该恶性肿瘤是上皮组织来源的,则在上皮名称后面加一“癌”字。如果是间叶组织来源的,则被称为肉瘤。例如,生長在肝臟的惡性腫瘤命名即為肝臟上皮細胞腫瘤(英语:hepatocellular carcinoma),或简称为更常见的“肝癌”;發生在脂肪細胞則稱作脂肪肉瘤。而骨肉瘤则是间叶组织来源的。如果一恶性肿瘤既有癌的成分,又有肉瘤成分,则被称为癌肉瘤。
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:

另一方面,現在有些方法則是想利用身體本身的免疫系統產生非專一性的免疫反應來對抗癌細胞,例如卡介苗膀胱內灌注免疫療法(英语:intravesical BCG immunotherapy)將卡介苗灌注進入膀胱內,以引發免疫反應對抗表淺性膀胱癌(英语:superficial bladder most cancers)。此外使用干擾素和介白質素,均可引起免疫反應。而使用疫苗所產生的免疫反應來對抗腫瘤的研究也正在進行當中,尤其是針對惡性黑色素瘤與腎細胞腫瘤(英语:renal cell carcinoma))。
某些癌症的成長會受某些荷爾蒙的增加或減少而抑制。對荷爾蒙敏感的腫瘤常見的例子有乳癌和前列腺癌,減低或增加體內雌激素或雄激素往往可用來做為補充治療的一種。
