31-year-old Sam Davies had a birthmark on her forehead for all of her life.  But when she was 32 weeks pregnant, the birthmark exploded. Which sounds awful, but it probably saved her life.

She was initially just stitched up, but when she went in for a check-up a year later, doctors found three tumors. Thankfully, they've all been removed. Sam has a scar and will need reconstructive surgery, but she's alive, and that's what matters.
