A hysteroscope can see lesions in the cervical canal. During a hysteroscopy, because the mirror travels through the vagina and through the cervical canal to the uterine cavity, it will see lesions in the cervical canal. A common cervical canal lesion is a small cervical canal polyp. If the polyp is small, it can be removed during the hysteroscopy, and the operating system of the hysteroscopy is equipped with miniature forceps and miniature scissors, which can be used to remove small lesions during the examination. If the cervical canal is relatively large, because it is close to the vagina you can dilate the cervix and remove the cervical canal with oval forceps or a small scraper, and then look at the cervical canal again with a hysteroscope to see if there is any residue.
