As an important part of a woman’s body, the cervix is also an organ that is more susceptible to disease, so cervical screening is essential. So far, the main types of cervical screening are cytology, hpv testing and colposcopy. Cytology is the detection of cancerous cells by tct or Pap smear, and tct is usually more accurate. The hpv test detects the presence of the hpv virus, which is a virus that can cause cervical cancer and is transmitted mainly through sexual intercourse. Patients who need hpv testing usually have erosion and bleeding on the surface of the cervix, increased leucorrhea and odor in the slightly severe cases, persistent pain in the buttocks and the roots of the thighs, and urination and defecation disorders. Colposcopy determines the condition of the cervix morphologically and histologically and improves the accuracy of the diagnosis of cervical cancer and precancerous lesions. It is a complementary test to cytology. Generally, if cytology is performed and suspicious cancer cells are found, colposcopy should be performed and biopsies should be taken for pathological examination. The accuracy rate of cervical screening modalities is now high. It is recommended that women, especially married women over 25 years of age, should undergo cervical TCT and HPV screening once a year.
