S2E93 - Detect Breast Cancer Earlier—Without Radiation? AI Thermal Screening Explained (Geetha Manjunath)

What if early breast cancer detection didn’t require compression, radiation, or hospital-grade machines?
In this powerful episode of Onion Soup, Dexter interviews Dr. Geetha Manjunath—computer science PhD, former principal scientist at HP Labs, and founder of Niramai—about how losing two close family members to breast cancer sparked a mission to rethink screening from the ground up.
Dr. Manjunath explains how Niramai uses infrared thermal imaging combined with artificial intelligence to analyze approximately 400,000 temperature data points from the body’s surface. Instead of radiation, the system identifies subtle thermal and vascular patterns that may indicate abnormal tissue activity.
The AI generates a probability score and highlights areas requiring further diagnostic follow-up.
Key insights from this conversation:
• Non-invasive, radiation-free screening
• No painful compression
• Portable setup for camps and primary care clinics
• Ability to detect lesions as small as 4 mm
• Potential to identify precancerous thermal changes earlier
• Monitoring over time for pattern shifts

Geetha discusses how portability expands access—particularly in underserved communities—making proactive health screening more scalable and equitable.

The episode also dives into the responsible use of medical AI. Dr. Manjunath emphasizes the importance of clinical validation and regulatory approval, noting Niramai’s regulatory clearances in India, CE marking in Europe, and US FDA authorization. She urges listeners to demand transparency, published studies, and regulatory backing when evaluating health technologies.
For women navigating midlife—balancing careers, caregiving, and their own health—this episode speaks directly to a core concern: how to stay ahead of risk without adding more stress to the body.
It’s a conversation about innovation, prevention, and empowering women with more options in their healthcare journey.
Because resilience begins with awareness.

And early detection can mean everything.
