Early menarche may be important in development of aggressive breast cancer in African-American women
A multicenter research team known as the African American Breast Cancer Epidemiology and Risk Consortium (AMBER), which includes UNC Lineberger's Andrew Olshan, PhD has uncovered differences in ER-positive & ER-negative breast cancer pathways. The team examined whether relationships between age at menarche and breast cancer are the same for tumors that are ER-positive or ER-negative, particularly among African-American women. ER-negative breast cancer is generally more aggressive and known to be associated with a poorer prognosis than ER-positive disease.
