Baby With Rare Tumor Born Twice, Now Healthy 4-Week-Old

Little Macie McCartney was welcomed into the world not once — but twice.

Four months into Keri McCartney's pregnancy, doctors reportedly noticed a tumor growing on the baby's tailbone.

Doctors discovered that the tumor was stealing blood from the fetus and weakening her heart. So, at 25 weeks, surgeons at Texas Children's Fetal Center cut into McCartney's abdomen in an effort to remove the life-threatening mass, according to a CBS News report.

“Prenatal surgery is still done in very few select areas in the United States,” Dr. Manny Alvarez, FOXNews.com's managing health editor, said Monday. “And there are a limited number of medical conditions where prenatal surgery is indicated and this is one of them.”
