in 2013-2014, lbbc carried out the first needs assessment of women diagnosed with triple-negative breast cancer (tnbc). approximately 10-20 percent of breast cancers are triple-negative, with a higher prevalence (30%) among african-american women. young hispanic women, premenopausal women, and women who test positive for the brca1 gene mutation, also have a higher prevalence of tnbc diagnosis. the study found that tnbc-diagnosed women had a greater interest in finding diagnosis-specific resources. it also found a greater degree of fear, anxiety, and worry among tnbc women than among those with other cancer diagnoses.
