Cancer during pregnancy presents considerable challenges that arise from various factors, including the diagnostic, prognostic and therapeutic implications of managing cancer in this unique patient population. There is a crucial need for an integrated approach that aligns medical interventions for both the pregnant patient and the developing embryo or fetus. Furthermore, the distinct characteristics associated with each stage of gestation may significantly influence the treatment protocols that can be proposed. Due to all of these factors, the importance of collaboration among healthcare professionals from different specialties (to ensure that both mother and child receive optimal care throughout the pregnancy) is often neglected. This review is designed to provide a thorough overview of the current standard procedures regarding the diagnosis and treatment options for cancer in pregnant patients in order to ensure the safety of mother and child. Furthermore, the review describes the feasibility of current fertility preservation methods, highlights the psychological effects of cancer during pregnancy and examines the risks and benefits of breastfeeding.
