Colposcopy is a procedure that gives your healthcare provider a magnified view of the cervix. It is done using a lighted microscope called a colposcope. In most cases, a sample of cervical cells is taken during a biopsy. The sample can then be studied in a lab. If any problems are found, you and your healthcare provider will discuss treatment options. It usually takes less than 30 minutes, and you can often go back to your normal routine right away.
