Key clinical point: Breast cancer survivors are less likely to conceive and have more complications when they do, but pregnancy does not increase the risk of cancer recurrence, a review suggests.

Major finding: Relative to the general population, breast cancer survivors were 60% less likely to become pregnant, and they had higher odds of complications such as preterm birth (45% higher) and low birth weight (50% higher), but their risk of cancer recurrence was not increased.

Study details: A systematic review and meta-analysis using data from 39 studies that included a total of 114,573 breast cancer patients and 8,093,401 women from the general population.

Disclosures: The study was funded by the Italian Ministry of Health and the Italian Association for Cancer Research. Dr. Blondeaux disclosed no conflicts of interest.
