A new study suggests that a pregnancy after treatment for early-stage, estrogen receptor (ER)-positive breast cancer does not affect the recurrence rate (J Clin Oncol. 2013;31:73-79). A previous meta-analysis had suggested a lower risk of breast cancer recurrence in patients who experienced a subsequent pregnancy, but this was believed to be possibly due to selection bias, because patients who become pregnant are usually those without recurrence (Eur J Cancer. 2011;47:74-83). In addition, none of the previous studies addressed the effect of pregnancy in patients with ER-positive disease specifically.
