A lighted magnifying instrument used to check the cervix, vagina, and vulva for signs of disease. The procedure is a colposcopy. During colposcopy, an instrument called a speculum is inserted into the vagina to widen it so that the cervix can be seen more easily. A vinegar solution may be used to make abnormal tissue easier to see with the colposcope. Tissue samples may be taken using a spoon-shaped instrument called a curette and checked under a microscope for signs of disease. Colposcopy may be used to check for cancers of the cervix, vagina, and vulva, and changes that may lead to cancer.
