放射線治療(也稱放療、輻射療法)是使用輻射線殺死癌細胞,縮小腫瘤。放射治療可經由體外放射治療(英语:exterior beam radiotherapy)或體內近接放射治療。由於癌細胞的生長和分裂都較正常細胞快,藉由輻射線破壞細胞的遺傳物質,可阻止細胞生長或分裂,進而控制癌細胞的生長。不過放射治療的效果僅能侷限在接受照射的區域內。放射治療的目標則是要儘可能的破壞所有癌細胞,同時盡量減少對鄰近健康組織影響。雖然輻射線照射對癌細胞和正常細胞都會造成損傷,但大多數正常細胞可從放射治療的傷害中恢復。因此通常在臨床上,醫師與放射專家會小心計算需要的放射線劑量,同時放射治療也會分成許多次進行,讓健康的組織在每次輻射線照射的間隔中能有機會恢復。

癌症是全球排在第二位的死亡原因。不过,随着癌症筛查、治疗和预防的改进,多种癌症的生存率有所提高。
药物治疗通常可分为:并发症治疗药物以及癌症靶向治疗药物。前者通常是治疗 患癌后出现的一些并发症如局部感染、病毒感染和疼痛。这类药物本身并不能治疗 癌症,但是能减轻患者的痛苦程度。而后者即常说的化疗,有多种类型,常见药物 有利妥昔单抗、曲妥珠单抗等。这些药物对肿瘤更有针对性,效率高、疗效显著、 不良反应较少。但仅适用于具有某类靶点的肿瘤患者,具有局限性;而且治疗费用 较高,可能会出现耐药性(即药物失效),很难实现治愈。
包括新辅助化疗、围手术期化疗、辅助化疗、根治性化疗、诱导化疗、巩固性化疗、姑息性化疗、维持化疗、转化性化疗、低剂量节律化疗等。
