How Biotech Startups Use Liquid Biopsies for Early Cancer Detection
from Biotech Business with Fexingo: Life Sciences Startups, Drug Discovery, and FDA Approvals · host Fexingo
In this episode, Lucas and Luna explore how biotech startups are using liquid biopsies — blood tests that detect circulating tumor DNA — to catch cancer earlier than traditional imaging or tissue biopsies. They dive into the case of Guardant Health, which has processed over 700,000 liquid biopsy tests, and discuss the technical challenge of picking up a single mutated DNA fragment among 50,000 normal ones. Luna challenges Lucas on sensitivity trade-offs, and they touch on how companies like Grail are aiming for multi-cancer screening at Stage I or II. No hype, just the data on what this technology can actually deliver today. Perfect for operators and builders in the life sciences who want to understand the clinical and business reality behind the headlines. #LiquidBiopsy #EarlyCancerDetection #CirculatingTumorDNA #GuardantHealth #Grail #BiotechStartups #PrecisionOncology #CancerScreening #CellFreeDNA #NextGenSequencing #Business #Technology #LifeSciences #DrugDiscovery #FDAApprovals #FexingoBusiness #BusinessPodcast #BiotechBusiness Keep every episode free: buymeacoffee.com/fexingo
