    Yes. In view of pregnancy, patient should be put on NACT AC for 4 cycles and followed by BCS. After that baby should be delivered and followed by further management. Hormonal treatment and radiotherapy are contraindicated in pregnancy.

    Gestational breast cancer is defined as diagnosis of breast cancer during pregnancy, 1st postpartum year or during lactation. As in non-pregnant women, surgery is the definitive local treatment and poses minimal fetal risk during any trimester of pregnancy.1-3 Mastectomy has the benefit that it may eliminate requirement for breast irradiation. BCS can be used effectively with delay of breast irradiation until after delivery.4-6 Sentinel lymph node biopsies (SLNB) during pregnancy is controversial7,8 and axillary lymph node dissection (ALND) is the standard approach for pregnant patients. Regarding systemic therapy, It is safe to administer most chemotherapeutic agents used in treating breast cancer during pregnancy after the first trimester. However, there is limited data regarding dose-dense schedule compared with treatment administered every three weeks.9 The latter allows for exclusion of pegfilgastim, for which there is insufficient human data to recommend administration during pregnancy. Filgrastim can be safely administered in trimester 2 and 3 if GCSF support is required. There is insufficient data on the safety of taxanes during pregnancy and therefore when possible should be delayed until delivery. References: 1. Woo JC, Yu T, Hurd TC.
