“…After delivery, prolactin induces milk accumulation and corresponding lobular growth and expansion, and these physiological changes lead to increased breast volume, nodular sensation and density [9]. These changes make the diagnosis of breast disease in pregnant or breastfeeding women more di cult, and some breast cancers are detected and diagnosed late [10,11].…”

Background and Purpose Pregnancy associated breast cancer (PABC) has attracted more attention recently. Previous studies have focused on comparison between the prognosis of PABC and non-PABC. This study aimed to investigate the correlation between parity and prognostic factors of PABC. Methods In this retrospective study, patients with PABC who underwent surgery at Fudan University Shanghai Cancer Center between 2017 and 2021 were analyzed. Data concerning tumor characteristics, reproductive history and survival outcome were recorded. Results In total, the median age of 203 patients enrolled was 34 years (range, 22 years to 46 years). Compared with primiparous group, multiparous group had higher rate of clinical stage III ~ IV [33.9% (41/121) vs 18.3% (15/82), P < 0.001], higher rate of IDC of histological grade III [72.9% (62/85) vs 62.5% (40/64), P = 0.002], higher rate of lymphatic metastasis [57.0% (69/121) vs 41.5% (34/82), P = 0.030]. Among the patients who underwent neoadjuvant chemotherapy, multiparous group had higher rate of pathological complete response than primiparous group [57.8% (26/45) vs 34.4% (11/32), P = 0.043]. The 2-year disease-free survival rate of primiparous and multiparous group were 82.0% and 74.2% respectively (P = 0.212). Conclusions Multiparity was correlated with worse prognostic factors in PABC patients, but no evidence suggesting correlation with worse survival yet.

“…Therefore, it is crucial that radiologists understand those changes. A review article published in the previous issue of Radiologia Brasileira addresses such physiological changes, the safety of breast imaging methods, and the main findings of breast diseases that occur during that period ( 3 ) .…”

MRI Evaluation of the Lactating Breast

et al. 2022

Purpose of Review To review the MRI appearance of physiologic lactational changes, common benign pathologies, and malignancies in the lactating breast. Recent Findings The prevalence of pregnancy-associated breast cancer has increased as more women delay childbirth and lactation. There is a transient increase in breast cancer risk after delivery when women may be lactating. MRI is more sensitive than mammography and ultrasound for the evaluation of the extent of disease in lactating women. Summary Understanding the key MRI findings of benign and malignant pathologies in the lactating breast is critical for accurate diagnosis and prompt evaluation of pregnancy-associated breast cancer.
