The chance of pregnancy after chemotherapy will depend on the age of the patient and her diagnosis. In the presence of the high estrogen and progesterone milieu of pregnancy, there have been concerns that pregnancy after breast cancer could stimulate micro‐metastases and increase the risk of disease recurrence, particularly in women with hormone receptor positive breast cancer. Current data have not shown an adverse impact on survival for those women who became pregnant regardless of the hormone receptor status of the primary tumor [15]. Interestingly, several studies have shown a better survival in women who achieved a pregnancy compared with those who did not, perhaps due to a “healthy mother effect” (i.e. women who achieve a pregnancy being a better cancer prognosis group [19,22]).
