Cervical neoplasia.

Cervical intraepithelial neoplasia is common in young women, and invasive cervical cancer is one of the most common malignancies seen in pregnancy. Women with cervical cancer diagnosed at <20 to 24 weeks of gestation are typically treated immediately, whereas patients diagnosed later in pregnancy often defer treatment until after delivery. Women with early stage cervical cancer can be treated with either surgery or radiation, whereas those with advanced-stage disease are usually treated with radiation, often in combination with chemotherapy.
