A. Heather Eliassen

Eliassen studies lifestyle factors and breast cancer risk.^[3] She made use of the Nurses' Health Study to better understand how women adapt their lifestyles to reduce their risk of breast cancer. She showed that adolescent consumption of red meat was associated with premenopausal breast cancer, whilst intake of poultry resulted in a lower risk.^[4] Additionally, she showed that high fiber^[5] cruciferous and orange vegetables reduce the risk of breast cancer.^[6][7]

Eliassen's research has shown that weight loss and increased exercise can reduce breast cancer risk after menopause.^[1][8][9] She also showed that increased levels of carotenoids in blood reduced breast cancer risk, with low risk of lethal breast cancer in people with high levels of carotenoids. Eliassen showed that high levels of circulating trans fatty acids was positively correlated with breast cancer risk, which was particularly high for overweight women.^[1]

In 2007, Eliassen was made Director of the Brigham and Women's Hospital Biorepository and in 2009 Associated Director of the Nurses' Health Study.^[10][11]
