I was watching an old documentary about six months ago, about dogs who have saved their owners' lives by sniffing cancer growths.
One lady said her dog wouldn't stop putting its paws on her chest and she was really annoyed at the dog's behaviour but she felt her breasts and there was a tiny lump there that she hadn't noticed before. She went to the doctor and it was an early sign of cancer.
Luckily she had treatment and she is now in good health.
