Chance of ivf leading to breast cancer?

Probably not: Every few years, someone makes the claim of a statistical link between in vitro fertilization and new diagnosis of breast cancer. A decade ago, the supposed increase was attributed to more intensive surveillance in these patients for early breast cancers. The new claim makes little sense biologically; please do keep up watching for breast cancer as you would ordinarily if you choose ivf.

Uncertain, but low: It's a great question that will remain open until the 'magic bullet' appears; but no good quality evidence exists to clearly support an association. I tell my patients that if an increased risk does exist, it's clearly very small and hard to prove.
