Decision-making for bilateral risk-reducing mastectomy for an increased lifetime breast cancer risk: A qualitative metasynthesis.

OBJECTIVE: Previvor is a term applied to a person with an identified, elevated lifetime cancer risk but without an actual cancer diagnosis. Previvorship entails the selection of risk management strategies. For women with a genetic mutation that increases their predisposition for a breast cancer diagnosis, bilateral risk-reducing mastectomy (BRRM) is the most effective prevention strategy. However, BRRM can change a woman's breast appearance and function. The purpose of this qualitative metasynthesis (QMS) was to better understand the decision-making process for BRRM among previvors. METHODS: A theory-generating QMS approach was used to analyze and synthesize qualitative findings. Research reports were considered for inclusion if: (1) women over 18 years of age possessed a genetic mutation increasing lifetime breast cancer risk or a strong family history of breast cancer; (2) the sample was considering, or had completed, BRRM; (3) the results reported qualitative findings. Exclusion criteria were male gender, personal history of breast cancer, and research reports which did not separate findings based on cancer diagnosis and/or risk-reduction surgery. RESULTS: A theory and corresponding model emerged, comprised of seven themes addressing the decision-making process for or against BRRM. While some factors to decision-making were decisive for surgery, others were more indefinite and contributed to women changing, processing, or suspending their decision-making for a period of time. CONCLUSIONS: Regardless of the decision previvors make about BRRM, physical and psychosocial well-being should be considered and promoted through shared decision-making in the clinical setting.

Body Image in BRCA-Positive Young Women Following Bilateral Risk-Reducing Mastectomy: A Review of the Literature.

Background/Significance: The presence of a breast cancer (BRCA) gene mutation increases a woman's lifetime risk of developing breast cancer. Bilateral risk-reducing mastectomy is a proactive treatment option which lowers that risk. However, breast removal can create a change in physical appearance. It is unclear if BRCA-positive women undergoing this surgery in young adulthood, a life stage where intimate relationships, families, and careers are being established, have the same experience with body image as women in later stages of life. Purpose: The aim of this literature review is to assess how bilateral risk-reducing mastectomy impacts body image in young BRCA-positive women less than 40 years of age, with no history of breast cancer. Methods: Database searches were performed, yielding 402 results. Studies were considered if participants had an increased lifetime breast cancer risk/BRCA-positive diagnosis and history of bilateral risk-reducing mastectomy, body image was evaluated, and mean age was less than 40 years. A total of three qualitative studies and three quantitative studies were identified as relevant for this review. Results: A dearth of information exists on body image in young women following bilateral risk-reducing mastectomy. It was found in this review that some women experienced a decline in body image following surgery, while in others body image was maintained or improved. Conclusion: Understanding factors that impact body image following this risk-reducing surgery will allow clinicians to support this unique population. Open and informative discussion should be encouraged with young women considering, or who have undergone, bilateral risk-reducing mastectomy.
