In the early stage of cervical cancer, the localization of cervix will not change accordingly, and the surface of cervix may appear erosion during gynecological examination, or it may be smooth, but the laboratory examination or pathological examination will find that the localization of cervix is cancerous, and it is recommended to deal with it positively in the clinic. If the cervical cancer enters the middle or late stage, the localization of the cervix may change, such as the appearance of cauliflower-like superfluous organisms, and the localization of the cervix may have contact bleeding, for example, when the gynecological examination touches the cauliflower-like tissues, it will cause bleeding, or it will lead to bleeding during coitus. Women should have a gynecological examination once a year to find out if there is any abnormality in the localization of the cervix and should have a cervical cancer screening test to find out if there is any disease in the localization of the cervix.
