The incidence is relatively increasing, thanks in part to improved detection methods, but also to the growing trend towards late childbearing. Material and methods. The features of breast cancer treatment during pregnancy were studied, and the effect of pregnancy on the long-term prognosis and clinical course of breast cancer was evaluated. Results. All patients received treatment according to the clinical recommendations. Chemotherapeutic treatment was performed in 44 (77%) patients, surgical treatment in 54 (96%) cases, radiation therapy in 40(72%) patients, and hormone therapy in 24 (42%) women. Among the newborns, there were no significant malformations, one child (a girl) had an underdevelopment of the left lung tissue, and laterphysical development in accordance with age. Conclusion.
