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：external 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。
另類醫學的治療方式包含許多種類的系統或療法，此類治療以現代醫學標準的觀點來看，通常不被認為是有效及安全的。但是醫師仍然可以利用這樣的治療方法來「補充」標準治療所不能提供的，例如身體的舒適或是心靈上的平靜，重燃起患者對治療癌症的希望。
