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episode, we explore how microfluidics, 3D co-cultures, endothelial layers, and real-time biosensing combine to replace outdated 2D cultures and reduce reliance on animal models.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.
