Dr. Matt Burgess interviews genetic counsellor and researcher Dr. Sibel Saya about integrating genetic testing into primary healthcare settings, focusing on polygenic risk scores as a tool for personalizing cancer screening.
• Genetic counselling principles applied in primary care settings rather than just specialist clinics
• Polygenic risk scores differ from traditional genetic tests by analyzing hundreds of common variants with small individual effects
• Australia and New Zealand have the highest bowel cancer rates globally, making early detection tools particularly important
• Tools like CRISP help assess individual bowel cancer risk using lifestyle factors combined with genetic information
• Cultural differences must be considered when implementing genetic testing in diverse communities
• GPs see genetic risk assessment as within their scope despite time constraints
• Risk information alone doesn't change behaviour – it's the opportunity to discuss screening that matters
• Implementation research happening alongside efficacy trials to speed translation into practice
• Stratified screening approaches could be widely available within 5-10 years
