What to know about chemotherapy in pregnancy

Cancer treatment in pregnancy is discussed by oncology, obstetric, and sometimes neonatal specialists. They consider the cancer type and urgency, the stage of pregnancy, the medicines proposed, and pregnancy-related changes in blood counts, kidneys, and liver. Some treatments are avoided during particular stages or close to delivery, while other options may be considered later in pregnancy. Monitoring can include blood tests, pregnancy assessments, and checks for symptoms such as anaemia or infection.

Tell every clinician that you are pregnant or might be pregnant before imaging, medicines, or procedures. Ask for a joint appointment or clear communication between teams. Discuss treatment timing, delivery planning, breastfeeding, fertility, contraception, and emotional support. Keep records of medicines, symptoms, appointments, and pregnancy assessments, and ask before taking over-the-counter products or supplements.

Contact the maternity or oncology team promptly for fever, chills, heavy bleeding, severe abdominal pain, fluid leakage, regular contractions, reduced fetal movement after you have been advised how to monitor it, breathlessness, or repeated vomiting. Use the emergency service for collapse, severe breathing difficulty, or uncontrolled bleeding.

Ask why treatment is recommended now, which medicines are suitable at this stage, how the baby will be monitored, how delivery timing may change, and what symptoms need same-day advice.
