I know dogs are used to find bed bugs and dogs act strangely before natural disasters occur, but is it possible for a dog to smell cancer? See, I would say no and think this is a woman who is remembering things differently after the fact. That being said, it would be interesting to see if it is possible. Brenda Jones says that for about a week her dog was acting strangely and would paw at Brenda's breast. At one point, the dog began to paw very hard and actually caused Brenda some pain. When she went to examine where the dog had hit her she noticed a lump and went to her doctor. The doctor said it was breast cancer and Brenda had the lump removed and is in chemo right now.
"I'm convinced Mrs Murphy could sense that I had a tumour - without her pawing me that day it would have gone undiagnosed. I am sure she targeted that part of my breast and I'll always be grateful that she sensed something was wrong."
