SciShow: Why Don't We Have Cancer-Sniffing Dogs?

Teacher or professor: SciShow
Subject: Science
Content of the Lesson: There are a lot of stories out there about dogs who seemed to smell lung cancer on their owner’s breath, and a recent study found that some dogs can detect lung cancer in blood samples with astonishing accuracy. So why aren’t there domestic dogs trained to detect cancer in every hospital on the planet? Hosted by: Hank Green SciShow has a spinoff podcast! It's called SciShow Tangents.
