Colon Polyps, Colonoscopy, and Colorectal Cancer in Pregnancy

Endoscopic evaluation is the main examination in the diagnosis of premalignant and malignant lesions of the gastrointestinal tract. Early diagnosis and treatment are possible by routine screening of people who have risk factors. It is diagnosed in advanced stages during pregnancy because of the pregnancy-associated symptoms masking CRC symptoms. CRC is more common in older ages. Due to the increasing maternal age in recent years, the risk of encountering CRC in pregnancy increases accordingly. Colonoscopy is an essential procedure in diagnosis. The risk and convenience of the procedure are different according to the week of pregnancy. Since the organogenesis of the fetus continues in the first trimester, anesthetic medications increase the risk of abortion with possible teratogenic effects.
