Pregnancy-Associated Breast Cancer: What Radiologists Must Know.

Pregnancy-associated breast cancer (PABC) is defined as breast cancer diagnosed during pregnancy, in the first year postpartum, or during breastfeeding. Imaging techniques play a significant role in the diagnosis of PABC. It is a challenging diagnosis since physiological changes seen in pregnancy and breastfeeding may limit clinical suspicion and imaging utility. The patient's well-being and the fetus must be taken into consideration for diagnosis and treatment.
