There is no blood inside a normal white belt. If a woman has a white belt with blood, she needs to consider a cervical disease or vaginitis, etc. This situation is definitely problematic and needs to be checked in a hospital. The more common causes of leucorrhea with blood are cervical erosion, cervical polyps, cervical precancerous lesions. In addition, severe pelvic inflammatory disease and vaginal inflammatory disease in the acute stage can also lead to leucorrhea with blood, which requires cervical cancer screening, focusing on excluding precancerous lesions of the cervix, as well as leucorrhea laboratory tests. Treatment with medication under the guidance of a doctor is required. If there is really a problem with the cervix, treatment by surgical means needs to be considered.
