Psychological distress and decision-making factors for prophylactic bilateral mastectomy in cancer-unaffected BRCA1/2 pathogenic variant carriers.

Objective: Women carrying a BRCA1/2 pathogenic variant have an increased risk for breast cancer and may opt for risk-reducing bilateral mastectomy. In this study, we examine which demographic, psychosocial, and personality factors are associated with their decision to undergo risk-reducing bilateral mastectomy.

Methods: Cancer-unaffected women with a pathogenic variant in BRCA1 or BRCA2 were recruited before receiving their genetic test result and completed follow-up including decision to undergo mastectomy over 6-8 months after genetic test result disclosure.

Survey on Physicians' Knowledge and Training Needs in Genetic Counseling in Germany.

Background: In recent years, germline testing of women with a risk of developing breast and ovarian cancer has increased rapidly. This is due to lower costs for new high-throughput sequencing technologies and the manifold preventive and therapeutic options for germline mutation carriers. The growing demand for genetic counseling meets a shortfall of counselors and illustrates the need to involve the treating clinicians in the genetic testing process.
