In 2022, the Centers for Disease Control and Prevention reported that there were almost 300,000 new cases of invasive breast cancer, 51,400 new cases of non-invasive breast cancer, and that breast cancer accounted for 30% of all cancers affecting biological females. This presents a public health burden of increased health cost, premature death, and a psychological burden of quality of life for survivors. Genetic testing holds great promise, but access is not equal. The objective of this capstone project is to explore the literature to identify interventions and recommendations to eliminate disparities in access to genetic testing for breast cancer. A scoping review of the literature from January 2000 to December 2022, using search terms interventions, disparities, breast cancer, genetic testing, and genetic counseling was conducted. Thirty articles were identified, 17 titles and abstracts screened, 13 full text articles were selected, and 7 were selected for review. The scoping review revealed that there are intrinsic and extrinsic barriers to access. A major extrinsic barrier is the primary care physician’s (PCP) lack of genetic knowledge and the underutilization of test referrals. It is recommended that the PCP take advantage of continuation education with a focus on genetics and the role of the genetic counselor. Another finding is that the more information gained from genetic counselling the greater the opportunity for the affected individual to make informed decisions. Racial and ethnic health disparities in breast cancer outcome persist despite many interventions and unequal access to testing means disparate experiences of disease.
