Cervical dysplasia refers to abnormal changes in the cells on the surface of the cervix. The cervix is the lower part of the uterus (womb) that opens at the top of the vagina.
The changes are not cancer, but they can lead to cancer of the cervix if not treated.
Cervical dysplasia can develop at any age. However, follow-up and treatment will depend on your age. Cervical dysplasia is most commonly caused by the human papillomavirus (HPV). HPV is a common virus that is spread through sexual contact. There are many types of HPV. Some types lead to cervical dysplasia or cancer. Other types of HPV can cause genital warts.
The following may increase your risk for cervical dysplasia:
Most of the time, there are no symptoms.
Your health care provider will perform a pelvic exam to check cervical dysplasia. The initial test is usually a Pap test and a test for the presence of HPV.
Cervical dysplasia that is seen on a Pap test is called squamous intraepithelial lesion (SIL). On the Pap test report, these changes will be described as:
You will need more tests if a Pap test shows abnormal cells or cervical dysplasia. If the changes were mild, follow-up Pap tests may be all that is needed.
The provider may perform a biopsy to confirm the condition. This may be done with the use of colposcopy. Any areas of concern will be biopsied. The biopsies are very small and most women feel only a small cramp.
Dysplasia that is seen on a biopsy of the cervix is called cervical intraepithelial neoplasia (CIN). It is grouped into 3 categories:
Some strains of HPV are known to cause cervical cancer. An HPV DNA test can identify the high-risk types of HPV linked to this cancer. This test may be done:
Treatment depends on the degree of dysplasia. Mild dysplasia (LSIL or CIN I) may go away without treatment. Changes due to HPV infection may also go away without treatment or dysplasia.
Treatment for moderate-to-severe dysplasia or mild dysplasia that does not go away may include:
If you have had dysplasia, you will need to have repeat exams every 12 months or as suggested by your provider.
Make sure to get the HPV vaccine when it is offered to you. This vaccine prevents many cervical cancers.
Early diagnosis and prompt treatment cures most cases of cervical dysplasia. However, the condition may return.
Without treatment, severe cervical dysplasia may change into cervical cancer.
Contact your provider if your age is 21 or older and you have never had a pelvic exam and Pap test.
Ask your provider about the HPV vaccine. Girls who receive this vaccine before they become sexually active reduce their chance of getting cervical cancer.
