Management of a pregnant person with cancer can be complex and warrants a multidisciplinary approach to care. Recent data have demonstrated reassuring outcomes for pregnant persons and their offspring after treatment of many types of cancer in pregnancy. Treatment of cancer in pregnancy must be individualized based on the specific type and stage of cancer, gestational age at diagnosis, and the patient’s desire to continue the pregnancy. This document aims to aid clinicians by summarizing the principles of diagnosing cancer in pregnancy and counseling patients about their reproductive and treatment options. It provides current, evidence-based recommendations for the medical and obstetrical management of patients with cancer. The following are the Society for Maternal-Fetal Medicine recommendations: (1) we suggest that ultrasonography and non-contrast magnetic resonance imaging (MRI) be used as first-line imaging techniques in the evaluation of a pregnant person with suspected cancer (GRADE 2B); (2) although non-contrast MRI and ultrasonography are first-line diagnostic imaging modalities in pregnancy, we recommend that computed tomography (CT) with or without contrast, gadolinium contrast for MRI, and fluorine-18-fluorodeoxyglucose positron emission tomography plus CT (18-FDG-PET/CT) not be withheld from a pregnant person if clinically indicated (GRADE 1C); (3) we recommend initiating thromboprophylaxis for all patients with active hematological or gynecological cancers during pregnancy and considering thromboprophylaxis for all patients with nonhematological or nongynecological cancers during pregnancy, based on individual risk factors (GRADE 1C); (4) we recommend that surgery for the treatment of cancer not be delayed or withheld from a pregnant patient at any gestational age in pregnancy (GRADE 1C); (5) we recommend that chemotherapy generally be administered after 12 weeks of gestation, provided that the patient desires to continue  \nThis is an open access article under the terms of the Creative Commons Attribution-NonCommercial License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited and is not used for commercial purposes.  \n© 2026 Society for Maternal-Fetal Medicine.
