Many types of infections can cause abnormal cervical cell changes.
The most common cause of cervical cell changes is the
human papillomavirus (HPV). This viral infection
usually is not treated, but the abnormal cell changes can be treated if needed.
HPV is also the cause of genital warts. An
abnormal Pap test may be the first sign that a woman
is infected with HPV.
Other types of infection that can cause abnormal cell changes
include:
While these infections can cause changes in cervical cells, they do
not cause cervical cell
dysplasia or increase the risk of cervical cancer.
These types of infections can be specifically treated, and a follow-up Pap test
should be done no sooner than 4 months after treatment to allow the cervical
cell changes to return to normal.
