Wow! That is so cool, especially when a woman's dog Tangle’s superior sniffing skills led to the early discovery of a deep-rooted cancer tumor insider her breast tissue in 2009. I mean, that is honestly amazing. Also, why is there a high chance of stomach cancer in Japan? Is it the food? What does stomach cancer do to you? I wonder what cancer smells like. I think the dogs like the job, because dogs like getting praised, and they get raised when they smell the cancer, so they work harder to find it. Way to go dogs!
