RANK pathway and Mammographic Breast Density: A very dense breast on mammogram is one of the strongest risk factors for breast cancer, and many women in the United States have extremely dense breasts. There is, however, very limited knowledge on how to modify breast density to reduce breast cancer risk. Through a series of projects, Dr. Toriola is investigating the associations between RANK pathway, known RANK pathway genes with mammographic density in premenopausal women (funded by a Susan G. Komen Career Catalyst Award), and in mid-life postmenopausal women (R21), and how these can be targeted in primary prevention of breast cancer.
