BRCA1/2 Study Highlights Gaps in Timely Cancer Prevention for Women in British Columbia
A population-based study published in Gynecologic Oncology examined the uptake of risk-reducing interventions among 1,920 women with BRCA1 or BRCA2 pathogenic variants in British Columbia. The study found that while 71.8% of eligible participants underwent risk-reducing surgery to prevent ovarian cancer, only 25.4% received the intervention within the recommended age range. Researchers also observed a decline in bilateral mastectomy rates among women without a previous breast cancer diagnosis, highlighting the importance of individualized prevention strategies and informed decision-making.
The findings emphasize that many women learn of their BRCA-related cancer risk too late to benefit fully from timely preventive interventions. Of particular concern, 27 ovarian cancers and 89 breast cancers were diagnosed after participants had been informed of their genetic status. The researchers underscore the need for earlier genetic testing, improved access to preventive care, and ongoing support to help individuals make informed decisions about cancer risk reduction.
