Higher circulating anti-Müllerian hormone (AMH) levels are associated with increased breast cancer risk among premenopausal women, according to a study of blood samples from 62,437 women, including 539 who were later diagnosed with breast cancer and 539 matched controls. Researchers found:
• Higher plasma levels of AMH were associated with increased breast cancer risk (top vs bottom quintile OR=2.20).
• This association did not vary by invasive vs in situ disease or by estrogen receptor status.
• Associations were not significantly different by age at blood sampling or at diagnosis.
• Additional adjustment for plasma estradiol or testosterone yielded similar results.
