Breast cancer during pregnancy (BCP) is clinically rare. BecausevBCP occurs in a specific physiological period in women, it may cause pregnancy-related complications, seriously affecting women’s health. There is a current lack of standards for diagnosis and treatment. We performed a literature search in the pubmed website for articles from 2017 to 2022 using the keywords breast cancer in pregnancy, diagnosis, and treatment ,and then summarized the current situation and the problems in BC diagnosis and treatment during pregnancy, and provided a basis for standards.
