A medical instrument which magnifies, and is used to examine living tissue and any associated lesions in situ. I have only seen the word colposcope used in connection with a follow-up of an abnormal pap smear, an indication of potential cervical cancer. After such a result, a doctor may perform a procedure called a colposcopy to get a better look at a woman's vagina and cervix in order to diagnose her condition. In this case the colposcope is lighted.
