Her primary area of research interest is to investigate disparities in cancer across the continuum of care from secondary prevention to diagnosis, treatment and end of life. She is particularly interested in decision-making at the end-of-life care for older adults and patients with advanced cancer, and on how disparities in cancer screening and cancer care affect cancer outcomes in racial/ethnic minorities and other disadvantaged and vulnerable populations. Dr. McCarthy has also published studies describing determinants of and variablity in mammography use in older women as well as the relationship between regular mammography use and breast cancer outcomes in older women.
