Cervical dysplasia

Definition:

Cervical dysplasia is the abnormal growth of cells on the surface of the cervix. Although this is not cancer, this is considered a pre-cancerous condition. Depending on the extent of changes, the condition is further categorized as:

  • CIN I -- mild dysplasia (a few cells are abnormal)
  • CIN II -- moderate to marked dysplasia
  • CIN III -- severe dysplasia to carcinoma-in-situ (cancer confined to the surface layer of the cervix)

Alternative Names:
Cervical intraepithelial neoplasia (CIN); Precancerous changes of the cervix

Causes, incidence, and risk factors:

Less than 5% of all Pap smear test results find cervical dysplasia. While the cause is unknown, a number of risk factors have been identified. Most cases occur in women aged 25 to 35.

Other risk factors include:

  • Multiple sexual partners
  • Starting sexual activity before age 18
  • Having children before age 16
  • DES exposure
  • Having had sexually transmitted diseases, especially HPV (genital warts) or HIV infection
