Why Don't We Have Cancer-Sniffing Dogs?

The video discusses the potential of domestic dogs in detecting cancer through their ability to identify volatile organic compounds (VOCs) associated with cancer cells. Despite anecdotal and scientific evidence supporting their accuracy, practical challenges such as the need for handler feedback and the variability in dogs' performance limit their widespread use. The video also explores the development of electronic noses as a technological alternative, which could leverage the odor signatures identified by dogs to improve early cancer diagnosis.
