The presence of vaginal bleeding with every coitus must be highly emphasized clinically. It is recommended to go to the hospital for cervical cancer screening and gynecological examination to find out whether there are localized cervical organisms or cauliflower-like organisms, to exclude the possibility of cervical polyps or other cervical lesions. In addition, it is also necessary to do routine tests for leukorrhea to rule out vaginal inflammation caused by vaginal mucous membrane damage caused by bleeding after intercourse. Bleeding during coitus is called contact bleeding, and contact bleeding should be highly valued clinically, mainly because contact bleeding can occur in the early stage of cervical cancer, so it is important to do cervical cancer screening, and further treatment according to the results.
