Female cervical screening is usually done at the age of 21 for women who are sexually active. Female cervical screening is to brush the cervix and cervical canal to remove the cells shed from the cervix and then conduct laboratory tests, mainly to screen the cervix for precancerous lesions or cervical cancer. Women who are sexually active, usually over 21 years old, can do it, because nowadays some people have sex earlier, even in their teens, and have multiple sexual partners, the chances of contracting the virus will be higher, so it is recommended that women who have been sexually active for 3 years and those who have had sex over the age of 21 should undergo cervical screening. Cervical cancer is one of the malignant tumors that threaten women’s health. Cervical screening can provide early detection, early treatment and early prevention of cervical cancer, so cervical screening is very important. Cervical screening includes TCT (liquid-based cell) and HpV (papillomavirus) examination, and if there is any problem with these 2 basic initial screening, further cervical biopsy is needed to confirm the diagnosis. Any discomfort in the body should be promptly consulted for examination and treatment under the guidance of a medical professional.
