SUMMARY: For the past few decades, researchers have been exploring the possibility that cancer, possibly created by the growth of tumors, actually has a particular odor -- and dogs can pick up on that smell. Some doctors believe this area of research may lead to more efficient screening methods and cancer treatment procedures. Special correspondent Dr. Emily Senay reports.
EMILY SENAY (NewsHour): You’ve seen them on the streets helping the blind, at airports and train stations sniffing for explosives and at the scene of earthquakes searching for survivors. But ever since her family got a Doberman puppy, this 55 year old retired magazine editor from New York’s Staten Island believes there may be another way for dogs to save lives.
One night in the spring of 2011, a couple of weeks after getting a new puppy, Diane Papazian noticed her dog Troy behaving strangely.
DIANE PAPAZIAN: So, he’s in bed with us, and he is in between my husband and myself, and– so, his head is right here. And he is nuzzling up against my left side, and he keeps nuzzling, and he’s nuzzling, and he’s not stopping. And I’m thinking, what in the heck is going on with this dog? Cut it out, you know, that’s so annoying. What are you doing?
And– he kept doing it persistently, like it wasn’t just once or twice, it was for a few minutes that he kept nuzzling. So finally I said, what in the heck is he doing? So, I started to itch, because I’m highly allergic, and that’s when I felt the lump.
