In the case of early stage cervical cancer, vaginal bleeding may not occur normally, but may occur in small amounts after sexual intercourse, or after bowel movements or strenuous activities. As the disease progresses, irregular vaginal bleeding may also occur in normal times, not necessarily after sex. In some young women, prolonged periods and increased menstrual flow may occur, and in older women, postmenopausal vaginal bleeding may occur. Usually, there may be increased leucorrhea, and if there is a co-infection, the leucorrhea may present a foul odor. In the advanced stage of cervical cancer, pressure symptoms may appear, such as frequent urination, urgent urination and anal swelling may occur. Married women of childbearing age who have irregular vaginal bleeding should be checked for cervical lesions and be treated promptly if cervical lesions are found. Even if there is no cervical lesion, cervical cancer screening should be done once a year, and the screening items include cervical liquid-based cytology and HPV virus testing, etc.
