Brigham and Women's study finds women with higher carotenoid levels have reduced risk of breast cancer

  • Posted: December 7, 2012

Women with higher circulating carotenoid levels are at a reduced risk of breast cancer, according to a Brigham & Women's Hospital and Harvard Medical School study published December 6 in the Journal of the National Cancer Institute. Carotenoids, which are micronutrients found in fruits and vegetables, have been found to have anticarcinogenic properties.

Brigham & Women's is a component of the Dana-Farber Cancer Institute.
