Maureen Burns in Rugby, England has a 10-year-old mixed breed collie named Max who probably saved her life.  Max started actingly strangely, sniffing his owner's breath and rubbing against her right breast. 

Mrs. Burns discovered a lump but it did not show up on a hospital mammogram.  She convinced doctors to do a biopsy and sure enough, the tumor was malignant. 

She's had surgery to remove the lump, followed by radiation treatment, and her prognosis is excellent. Mrs. Burns is convinced that she is alive today because of her dog's keen sense of smell.

"It was his peculiar reaction that alerted me to the fact that something was wrong. At first I thought he was just getting old, he was not so playful and his eyes were sad. He'd sniff my breath in an odd way -- I even asked my husband Roger if I had halitosis."
