Abnormalities of the cervix usually need to be determined by specialized tests such as vaginal ultrasound, colposcopy, and cervical cytology. No abnormalities in the position of the cervix, the size and shape of the external opening, and normal amount and color of vaginal discharge usually do not cause cervical lesions. However, if you want an exact diagnosis, you need to use professional tests. Abnormalities of the cervix may be due to diseases such as cervical cysts, cervical polyps, cervical fibroids and cervical cancer. Vaginal ultrasound can check for cervical cysts, cervical polyps, cervical fibroids and so on.
