Bleeding after intercourse requires consideration of the following diseases: i. cervical erosion; ii. cervical canal polyps; iii. cervical cancer, which requires a gynecological examination at the hospital to find out if there are cervical lesions. If cervical erosion is present, further screening for cervical cancer exclusion is needed to rule out the presence of HPV infection and cervical cytology lesions. If cervical cancer screening is problematic, further treatment is needed; if cervical cancer screening is not problematic, oral hemostatic drugs or antibiotics are needed to avoid upstream infection; if erosion is serious, physical therapy can be used; if cervical canal polyps exist, cervical canal polyps removal is needed; cervical cancer requires surgery.
