Study in mice suggests that expression of estrogen-related gene can impact post-menopausal breast cancer risk

In a study using a first-of-its kind mouse model of aging that mimics breast cancer development in estrogen receptor-positive post-menopausal women, investigators at Georgetown Lombardi Comprehensive Cancer Center and colleagues have determined that over-expression, or switching on of the Esr1 gene, could lead to elevated risk of developing estrogen receptor-positive breast cancer in older women.
