Do you know that dogs can actually smell cancer? According to a BBC documentary, their sense of smell is so sensitive, that they can detect (and consequently get turned off by) harmful compounds from cancerous tumors!
The said clip narrates the amazing story of Maureen Burns and her dog, Max. Maureen observed that her nine-year-old dog has become depressed, so she slowly accepted the fact that she will soon lose her pet.
She did notice, however, that Max would always touch her breast using his nose—the one with a supposedly benign lump. She initially shrugged it off because she has always tested negative for cancer.
But due to her dog's unusual behavior, she finally decided to go for an operation—which revealed that the lump was actually cancerous! Max is now back to normal again, and Maureen is thankful for her second lease on life, all thanks to her furry best friend.
