A pair of sisters say that they discovered they each had breast cancer all thanks to a furry friend in their lives.

Amanda Tasca and her older sister Amy Niosi, who are both in their mid-30s, each discovered that they had the illness and are now crediting Tasca's canine companion Daisy with saving their lives, according to ABC7.

Per the report, Tasca discovered a tumor in her breast when Daisy jumped on her and caused some discomfort. "This one jumped on my chest and I was like, 'Ow, that kind of hurt,'" Tasca told the outlet while pointing to her pooch.

After the initial incident with her sister, Niosi then found a lump when she was watching television while wearing a T-shirt and no bra. When she had a bra on, she says she couldn’t feel the lump. Niosi later discovered that she had stage 3 breast cancer, as well as cancer in her lymph nodes.
