what is cervical dysplasia

Cervical dysplasia is a precancerous condition in which abnormal cell growth occurs on the surface lining of the cervix or endocervical canal, the opening between the uterus and the vagina. It is also called cervical intraepithelial neoplasia (CIN).

Strongly associated with sexually transmitted human papillomavirus (HPV) infection, cervical dysplasia is most common in women under age 30 but can develop at any age.

Cervical dysplasia usually causes no symptoms, and is most often discovered by a routine Pap test. The prognosis is excellent for women with cervical dysplasia who receive appropriate follow-up and treatment. But women who go undiagnosed or who don’t receive appropriate care are at higher risk of developing cervical cancer.

Mild cervical dysplasia sometimes resolves without treatment, and may only require careful observation with Pap tests every three or six months. But moderate-to-severe cervical dysplasia – and mild cervical dysplasia that persists for two years – usually requires treatment to remove the abnormal cells and reduce the risk of cervical cancer
