ABSTRACT


Introduction: Breast cancer is the most common cancer during pregnancy. When breast cancer is diagnosed during pregnancy or in the first year of postpartum, it is termed as pregnancy-associated breast cancer (PABC). Pregnancy-associated breast cancer affects one in every 30,000 pregnancies, with an increased incidence in recent years mainly due to higher maternal age at delivery.

Case Report: In this case report, we describe the case of 29-year-old woman diagnosed with PABC. She was diagnosed with breast cancer and conceived the same month. She underwent breast conservation surgery in the first trimester followed by chemotherapy in the second trimester. With multispecialty support we could prolong the pregnancy till 35+ weeks, post which a healthy baby was delivered by cesarean section. The case report explains the management and treatment protocol (surgery, chemotherapy, obstetrics management, and outcome).

Conclusion: Management and treatment protocol of PABC needs to be tailor made for the affected patient as there are multiple variables to be managed.

Keywords: Chemotherapy, Duct carcinoma, Mammography, Pregnancy-associated breast cancer
