More bleeding after cervical cancer screening may be more serious. Bleeding after cervical cancer screening is normal and not serious, usually bleeding will stop in 1-3 days and the longest time will not exceed 7 days. If bleeding is heavy after cervical cancer screening, it may be caused by local inflammation or organic lesions, such as cervical polyps, endometrial polyps, submucosal leiomyoma or cervical cancer. Heavy bleeding after screening is more serious if it is caused by cervical cancer. If there is cervical inflammation, cervical congestion or cervical erosion, etc., bleeding may be caused by touching the diseased tissues during cervical cancer screening, and these cases are not serious. Therefore, if you bleed a lot after cervical cancer screening, you must go to a regular hospital as soon as possible to have your condition analyzed and disposed of by a professional doctor.
