Bleeding from cervical screening samples is normal. Cervical screening includes screening for cervical TCT and HPV. Cervical cancer screening allows for an initial check for the presence of abnormal cells in the cervix, as well as cervical HPV infection, for early detection of cervical lesions. Depending on the results, screening can be done annually or every 2 to 3 years. Cervical cancer screening involves brushing the cells from the endocervix for laboratory tests. Using different special soft brushes to enter the endocervical opening and rotate it 5 to 7 times in a clockwise direction, there is some irritation to the endocervical opening, which can damage the small blood vessels at the opening of the cervix a small amount of bleeding occurs. Generally the bleeding will stop on its own within a short period of time and does not require special treatment. The presence of cervical inflammation in individual women may lead to heavy bleeding and require prompt treatment to stop bleeding. It is best to prohibit sexual intercourse for 3 to 5 days after the cervical screening sample to avoid cervical or vaginal inflammation and infection. In addition, if the bleeding symptoms of the cervical screening sample continue to be unrelieved, it is necessary to go to the hospital in time for treatment.
