A normal result from cervical cancer screening may be followed by an abnormal lesion one month later.
False-negative results can occur if the lesion is located deep within the cervical canal at the time of cervical cancer screening, or if the cervical biopsy fails to pick up the diseased tissue, resulting in a normal cervical cancer screening but an abnormal cervical lesion being detected one month later on a follow-up or due to abnormal symptoms.
HPV infection, multiple sexual partners, early sexual intercourse, smoking, and low immunity are all risk factors for cervical lesions. A normal cervical cancer screening result one month ago, but the persistence of risk factors, can also lead to cervical lesions.
If the result of cervical cancer screening is normal and there is no clinical manifestation such as vaginal bleeding, it is also recommended to have a regular review so as not to miss the lesion and delay the treatment.
