NCCN updated its Genetic/Familial High-Risk Assessment guidelines to include breast, ovarian, pancreatic, and prostate cancers, reflecting the latest genetic research. The guidelines now cover testing for genes like BRCA1, BRCA2, CDH1, PALB2, PTEN, TP53, and HOXB13, with specific management strategies for P/LP variants, including screening, surveillance, and preventive surgeries. These updates aim to enhance shared decision-making, screening practices, and targeted treatment choices.
