Episode notes
Need for Proactive Cancer Screening
- Cancer screening has very limited existing tools and most cancers have no screening tests available.
- There is a crucial need to shift from reactive to proactive cancer screening for earlier detection.
Prenatal Test Sparks Cancer Breakthrough
- Non-invasive prenatal testing detected chromosomal abnormalities in pregnant women that led to cancer diagnosis postpartum.
- This discovery inspired GRAIL's blood test development for early cancer detection.
Tumor DNA Shedding Key to Detection
- Circulating tumor DNA detected in blood is DNA shed from tumor cell turnover, not the cells themselves.
- GRAIL’s test filters tumor-specific DNA signals from a haystack of normal DNA for cancer detection and site origin.
