She is Board Certified in Internal Medicine (1997) and Medical Oncology (2000).

As a medical oncologist Dr Royce's on-going interest in breast oncology span the full spectrum of prevention, treatment of early and advance stage disease and survivorship, focusing on patient care through clinical trials. To this end, she serve(d) as a local site PI for 27 NCI-supported trials, 25 Industry-Sponsored trials (one as National co-PI and one as a member of the Steering Committee), and 10 Investigator Initiated institutional or multi-institutional trials.

The goal of these collaborations was to identify unique therapeutic targets, novel diagnostic techniques and unique etiologies of health disparities that can be translated into the clinical arena for improved care of breast cancer patients. In addition to understanding the biologic factors contributing to disparities in breast cancer survival among our racial/ethnic minorities, she was committed to developing programs to address disparities in screening, treatment and survivorship for the local rural and underserved communities. For the last 10 years, she was associated with the former New Mexico (NM) Minority Based Community Clinical Oncology Program and led the NM-MBCCOP since 2011.
