Cervical dysplasia is a condition that women can develop before developing cervical cancer. The condition is precancerous and is characterized by the growth of abnormal cells on the lining of the cervix or endocervical canal. Cervical dysplasia is also known as intraepithelial neoplasia. This condition is often associated with HPV, or human papillomavirus, which is a sexually transmitted infection. The condition is most common among women who are younger than thirty years old. However, women of any age can develop it.
