As women, we're always told how often we need to be getting mammograms or doing breast self-exams to stay on alert for breast cancer. And of course these tests are invaluable, but every now and then, the first warning of the disease could come from woman's best friend. Such was the case for Marian Cooper, who knew something was up when her 6-year-old pug, Flo, was fixated on her right breast. Cooper explains, "Flo kept nudging me and digging at me -- no matter how many times I put her on the floor, she would always climb back up. I thought she was just being annoying, but without her I'd probably be dead."
That's because when Marian finally decided to perform a self-exam, she realized she had a lump. Which turned out to be a grade 3 malignant tumor, doctors confirmed. Wow.
