Study : Women can have safe pregnancies after breast cancer treatment

Most relevant for: Women who have had breast cancer who are considering pregnancy.

In a large analysis of all published studies to date, most women who become pregnant after breast cancer treatment had safe pregnancies, with no increase in their cancer recurrence risk. Infants of mothers treated for breast cancer were more likely to have low birth weight, preterm birth and small size at birth but there was no increase in birth defects. Breast cancer survivors who became pregnant had a similar risk of recurrence and survival as survivors who did not become pregnant. (posted 6/24/21)

Most relevant for: Women in their childbearing years

Does having children alter the risk of breast cancer? Women who give birth have a lower lifetime risk of breast cancer. However, newer data suggests that breast cancer risk increases immediately after childbirth. A study published in December 2018 examines data from the Premenopausal Breast Cancer Collective Group seeking to clarify this issue. (12/28/18)
