切除 (qiē chú) is a transitive verb meaning 'to remove surgically'—typically referring to the excision of tissue, organs, or growths during medical procedures. The first character 切 (qiē) means 'to cut', often with precision or force, while 除 (chú) means 'to remove', 'to eliminate', or 'to get rid of'. Together, they emphasize a deliberate, clinical act of cutting out something unwanted from the body. This term is used almost exclusively in formal medical contexts—such as doctor-patient discussions, surgical reports, or health education—and rarely appears in casual conversation.

It is commonly paired with anatomical nouns (e.g., 肿瘤, 阑尾, 子宫) and often follows auxiliary verbs like 需要 (need to), 已经 (already), or 将要 (will). Unlike general terms like 去掉 (qù diào) or 拿掉 (ná diào), 切除 carries technical weight and implies a professional, sterile, and irreversible intervention. It may also appear in compound nouns like 切除术 (qiēchúshù, 'excision surgery').
