Hereditary gene mutations (such as BRCA1 and BRCA2) significantly increase the risk of breast and ovarian cancer. Genetic testing or blood tests for early cancer screening such as LucenceINSIGHT™ allows for the assessment of congenital cancer risk before any symptoms appear. If a high-risk mutation is found, a doctor can develop a personalized prevention plan, such as starting annual MRI scans at age 25-30 for precise prevention and early detection.
