An overarching theme in clinical literature suggests an inherent mistrust among populations of color within the healthcare system and the importance of healthcare professionals to bridge this gap in care. This is especially true when addressing cancer care in underserved populations due to mistrust in providers, diagnostic tools, and treatments. Ovarian cancer is difficult to diagnose early in all populations; however, women of color who have an intrinsic mistrust of the medical community will delay or refuse screenings or treatments that could be greatly beneficial. Similarly, although breast cancer rates are high in women of color, many are reluctant to utilize genetic screenings or counseling services due to bad experiences with healthcare, both personally and within their community. Moreover, transgender patients are at a unique disadvantage, as they face barriers to accessing culturally competent care while also being at a higher risk for developing cancer. The objective of this study was to conduct a scoping review of the literature in order to synthesize knowledge about the climate of mistrust between medical providers and racial, ethnic, and gender minorities with breast cancer and ovarian cancer. It is imperative for healthcare workers to acknowledge medical mistrust and strive to reduce internalized bias, increase their availability to patients, and ensure patients feel heard, respected, and well cared for during visits. Improving care by physicians can enhance trust between underserved communities and healthcare workers, encouraging all people to actively seek proper medical care and cancer screening, potentially resulting in a reduction of mortality and morbidity rates.
