Cancer of cervix is the most common pelvic cancer to occur during the reproductive period. Forty-three percent of women diagnosed with cervical cancer are younger than 45. It is estimated that 1–3% of cervical carcinoma patients will be pregnant. Colposcopy and directed biopsy in pregnancy present the safe and accurate tools for assessing the pregnant woman with abnormal cervical cytology. Pregnancy presents an opportunity for cervical cancer screening and education. The increasing hormonal and metabolic influences of pregnancy cause the intensive alterations, which can be easily monitored by the use of Colposcope. Two principal changes of the cervix in many pregnant women are the eversion of the endocervical canal with the gaping of the external OS and decidualization. Finally, the effects of labour and vaginal delivery on the cervix and cervical epithelium must be considered. Therefore, it is best to defer further colposcopic assessment of women with abnormal cytology during pregnancy for about three months post delivery.
