After the birth of her fifth child, a woman's "simple birthmark" reportedly became "a monster" that could have ended her life.
Sam Davies, 31, of Skelmersdale, Lancashire, England, has had a birthmark on her forehead since she was a child, the Daily Mail reports. Throughout most of her life, she "learned to live with it" by covering it with bangs.
This mark also reacts to Davies pregnancies and has functioned as a pregnancy test over the years. When it starts to itch, she knows she’s pregnant.
"When I was pregnant with my first daughter, the birthmark started to grow a little, it became itchy and it grew," Davies said, according to the Daily Mail. “It was more of a growth than a mark and I hated it.”

After the birth of her first daughter, Davies had surgery to remove the outer part of the growth.
"With each of my daughters, it would itch and irritate, but it didn't grow beyond that," she explained.
However, by the time Davies was pregnant with her son, her fifth child, the birthmark was out of control. Healthcare professionals said the birthmark was reacting to the increase in her blood pressure.

"My doctors believe that the male hormones from carrying a boy were the trigger,” Davies said.
At 32 weeks, her birthmark exploded. She was taken to a hospital to halt the bleeding and stitch up her forehead. She was closely watched by doctors throughout the remainder of her pregnancy,
"The last two months of my pregnancy were horrendous,” Davies said. "As my bump grew, the birthmark grew too. It was like a monster."
Her son was born in March 2013. In May 2014, she started the first of several procedures to halt the development of the mark. Ultimately, Davies had surgery to remove three hemangioma, one of which contained some cancerous cells.
"Part of my skull was exposed after the surgery," Davies said. "It was horrific."
According to the Great Ormond Street Hospital for Children, hemangioma is a benign tumor that occurs in one in 10 children. About 80 percent of hemangioma do not develop any problems.
Davies’ tumors have been completely removed and she now has a scar where her birthmark used to be. She and her husband, Paul Davies, have decided to not have any more children "just in case the monster wakes up again."
