联想：invasive 以 in 开头，像『进入』；肿瘤进入并扩散是『侵袭性』，手术穿刺进入身体是『有创的』。
语域：formal 常见场景：medical reports、clinical discussions、pathology and oncology writing “invasive”通常出现在医学或科学语境中，属于正式用语，多用于描述需要进入身体的检查或治疗（如 invasive surgery），或描述疾病向周围组织扩散（如 invasive cancer）。日常口语中较少使用。
Genuine rhymes: persuasive, evasive, abrasive, and pervasive all share the stressed /eɪsɪv/ ending with invasive. Watch out: decisive and incisive look similar but have /aɪsɪv/, so they do not rhyme with invasive.
