MESA, AZ - Doctors are calling an 18-month-old a guardian angel after they say she saved her great-grandmother's life.
Elizabeth Grant tells ABC15 the toddler kept pointing at her swollen feet for days.
Family members finally decided to pay attention and took Grant to Banner Heart Hospital.
Doctors say foot swelling is a sign of severe heart failure.
"I thought she wanted me to put on my shoes, I never thought anything like this," said Grant.
Doctors did more tests and discovered that Grant also has stage three breast cancer.
"If it weren't for her, I never would have known that I even had cancer. She's my little angel," said Grant.
Grant is still waiting on the results of the tests to see if the cancer has spread anywhere else and if it can be treated.
