00:00Watch this beagle closely.
00:01She's checking these samples for one thing,
00:04and when she stops here, she may have just detected cancer.
00:09We've already used dogs to sniff out drugs,
00:12explosives and even COVID-19 infections.
00:15Now, Bengaluru start-up Dognosis wants to use their noses
00:20to screen human breath for signs of cancer.
00:23Patients breathe into masks that are sent to the company's facility.
00:26Dogs sniff out the samples, while sensors and AI track everything
00:31from their body language and breathing to brain activity
00:34to help identify a positive.
00:37In a study published in the Journal of Clinical Oncology,
00:40Dognosis reported roughly 90% sensitivity for early-stage cancers
00:45across seven broad groups spanning more than 20 cancer types.
00:49The start-up is now running a larger trial across 10 hospitals in India.
00:54If the results are validated,
00:56it plans to launch an at-home pre-screening tool in Bengaluru next year
01:00for a few thousand rupees.
01:02The bigger test is whether the performance holds up outside control trials.
01:08Going to market will also mean building the logistics
01:11to move and process a huge number of breath samples.
01:15And it's not alone.
01:16New Jersey start-up Spotted Early has reported similar results
01:20from its own canine detection trials.
01:22But so far, this kind of testing has yet to be commercialized.
