Episode notes

Cancer has overtaken cardiovascular disease as the leading cause of death in Ireland, yet our mortality rates are falling faster than anywhere else in Europe. What's driving this paradox? Professor Deirdre Murray, Director of the National Cancer Registry of Ireland, pulls back the curtain on how cancer data is transforming healthcare in this country.

Every year, the Registry captures data on approximately 24,000 new invasive cancer cases, plus 11,000 skin cancers. While this might sound alarming, Murray explains how this comprehensive collection method actually provides Ireland with more accurate statistics compared to countries that only sample portions of their population. The registry tracks three vital metrics: incidence rates, mortality figures, and survival statistics – all essential for effective cancer control.

The conversation takes fascinating turns through Ireland's screening programmes, where cervical screening has already begun reducing cancer incidence, and the revolutionary impact of the HPV vaccine, which is projected to make cervical cancer a rare disease by 2040. Murray dismantles common misconceptions about cancer, explaining why most patients are over 60 despite media portrayals focusing on younger patients, and why early diagnosis remains so crucial: "The earlier you go to get things checked out, the earlier the stage you are diagnosed, the less treatment you're going to need."

Perhaps most striking is Murray's revelation about Ireland's technological challenges. Despite being a tech-literate nation, Ireland ranks last among 22 developed countries for health digital policy and data linkages. With over 800 different systems operating across our public health sector alone, the fragmentation prevents the seamless information flow that could transform cancer care. As Murray puts it, "My local Tesco knows more about me than my local hospital does."

Whether you're concerned about cancer risk factors, curious about screening programmes, or interested in how data shapes healthcare policy, this episode offers invaluable insights into the present and future of cancer control in Ireland. Listen now to understand the remarkable progress we've made and the challenges that still lie ahead.
