Bleeding after internal gynecological examination does not necessarily mean cervical cancer, but it should be taken seriously and further examined. Because contact bleeding can also occur in the early stage of cervical cancer, cervical cancer screening can be performed. Of course, bleeding from internal examination is also related to gynecological diseases, such as cervical erosion, vaginitis, cervical polyps, etc. Cervical cancer is a common gynecological malignancy, 70% of which is caused by persistent infection with high-risk HPV virus, and also includes other factors, such as multiple births, multiple pregnancies, too many sexual partners, and early sexual life. Cervical cancer mostly occurs in married and fertile women. Women who have given birth are better off to have routine cervical cancer screening and timely treatment when viral infection or precancerous lesions are detected in order to stop disease progression, which can well prevent cervical cancer. When conditions are suitable, cervical cancer vaccine can be given. With the widespread implementation of cervical cancer screening, the incidence of cervical cancer has significantly decreased, and so has the mortality rate.
