LEWISVILLE, Texas (People) — Lynlee Boemer was just 1 lb., 3 oz. when doctors removed a tumor from her body that weighed almost as much as she did.
At just 23 weeks, she was taken from her mother Margaret Boemer’s womb for 20 minutes so doctors could perform a five-hour, life-saving surgery. The surgeons then placed Lynlee back inside the womb and sewed the uterus shut.
Margaret says she didn’t think twice about going through the open fetal surgery.
“I knew we were doing this to try and save her life,” Margaret from Lewisville, Texas, tells PEOPLE. “That’s all I could focus on.”
