chemotherapy 拆成 chemo(化学) + therapy(治疗)：化疗就是用化学药物治病；把“化学疗法”缩成“化疗”来记。
语域：neutral 常见场景：medical consultations、patient education、treatment discussions chemotherapy 是标准的医学术语，通常用于医疗文书、医患交流和健康科普中；在日常谈论癌症治疗时也比较常见。整体语气中性偏正式，正式和一般性场合都可以使用。
这些词都以 -therapy /θɛrəpi/ 结尾，重音都在 -ther- 上，与 chemotherapy /ˌkimoʊˈθɛrəpi/ 押韵。注意：therapy 与 theory /ˈθɪri/ 拼写相似但读音不同；chemo- 中的 e 读 /ɛ/，不是 /iː/。
