How Tumor-on-a-Chip Technology Is Transforming Cancer Treatment and Drug Testing

What if the tools we use to test cancer drugs don’t behave like human tumors at all? That’s the question that pushed Ghazaleh Madani, CEO and co-founder of CanChips, to build one of the most compelling innovations in oncology today: tumor-on-a-chip platforms that replicate human tumor biology with unprecedented accuracy. In this episode, we explore how microfluidics, 3D co-cultures, endothelial layers, and real-time biosensing combine to replace outdated 2D cultures and reduce reliance on animal models. The result: faster, more predictive cancer drug testing — and a pathway toward truly personalized oncology. Our sponsor:🚀 Exclusive Black Friday offer – NordStellar x Startuprad.io.
