A recent study reported that pregnancy after breast cancer was safe for both mother and baby.1 Specifically, the researchers found that pregnancy after breast cancer was not associated with adverse maternal prognosis or fetal outcomes. Another study reported that breast cancer after pregnancy could be associated with poorer outcomes. Specifically, breast cancer diagnosed within 10 years of having a child was associated with a higher risk of mortality, especially in BRCA1 carriers.2 This information could be important for genetic counseling, prevention, and treatment strategies in BRCA1/2 carriers.
