British black women are more likely to have estrogen-receptor-negative breast cancer and to get the disease at a younger age than white women, according the research published in the British Journal of Cancer . The clinical study, of black patients from 1994 to 2005 at an East London hospital, determined that these women:
• Were diagnosed at a median age of 46, or 21 years younger than white women.
• Had a higher rate of more advanced tumors and lymph-node involvement.
• Were more likely to have triple-negative tumors.
Results of this study are reflective of earlier research on African-American women.
