Women of Mexican descent diagnosed with breast cancer were twice as likely to present with triple-negative disease than other subtypes if they had a family history of breast or ovarian cancers, according to study results presented at the American Association for Cancer Research Conference on the Science of Cancer Health Disparities in Racial/Ethnic Minorities and the Medically Underserved in San Antonio.
“Triple-negative breast cancer is one of the worst breast cancer subtypes in terms of outcomes,” Maria Elena Martinez, PhD, Sam M. Walton endowed chair for cancer research and professor in the department of family and preventive medicine at the University of California, San Diego, Moores Cancer Center, said in a press release. “Our finding that family history is related to breast cancer subtype for Hispanic women of Mexican descent has tremendous implications for breast cancer treatment, screening and prevention among this population. It not only affects decisions around treatment plans for patients, but extends to screening and prevention plans for family members.”
