Bleeding after intercourse, whether coffee-colored or bright red in color, is an abnormal phenomenon and should be taken seriously. It is mainly caused by localized lesions of the cervix, and coffee-colored discharge caused by vaginal organisms, or breakage of the vaginal mucosa cannot be ruled out in clinical practice. It is recommended to do gynecological examination to understand the specific situation in the vagina, and to know whether the cervix has cauliflower-like tissue. It is also recommended to do cervical cancer screening to find out if there is epithelial lesion on the cervical epithelium or if there is a high-risk HPV infection, and to give timely treatment to any abnormal problems found. Women who experience coital bleeding, no matter what color it is, should pay attention to it, and the most common clinical condition is the early stage of cervical cancer.
