Researchers at Moffitt Cancer Center and colleagues in Canada have published study results focused on black women younger than 50, a population disproportionately afflicted with and dying from early-onset breast cancer compared to their white counterparts. The research published in The Breast Journal.
Early-onset breast cancer has been associated with mutations in the BRCA1 and BRCA2 genes. These breast cancer–predisposing genes were discovered almost 20 years ago and confer a lifetime risk of breast cancer of 60% to 70%, as well as a much higher risk of a second primary breast cancer compared to noncarriers. The researchers suggest that genetic counseling and BRCA testing can reduce cancer incidence and mortality in those identified with mutations."
