Pregnancy does not affect the course of the cancer itself. However, diagnosis is often delayed as the presenting symptoms of malignancy may be confused with the common symptoms of pregnancy. The symptoms of cancer and of normal pregnancy overlap and can easily be confused. Early satiety, nausea and vomiting, constipation, dyspnoea, fatigue and depression are all common during a normal pregnancy but can also be significant symptoms of malignancy. Lactational adenomas, galactoceles, mastitis and infarction of hypertrophied breast tissue are all benign pregnancy-induced breast lumps that may masquerade as malignancy. Cervical cancer is normally staged clinically by chest X-ray, cystoscopy, urogram and fluorine-18-labelled fluorodeoxyglucose (¹⁸FDG) CT scanning or magnetic resonance imaging (MRI). Cancers presenting at less than 20 weeks’ gestation have traditionally been treated immediately. With the extensive use of ultrasound for dating and assessing pregnancies, the recognition of adnexal masses in pregnancy has increased.
