A baby was removed from womb for surgery and then eventually returned inside for her actual birth, making her the first baby to be born twice.

According to News.Au.com, her mother, Margaret Boemer, who was then 16 weeks-old pregnant , had a customary ultrasound. During which, the doctors who examined her found a tumor on her baby's tailbone, a medical condition called Sacrococcygeal teratoma.

The report added that the only way the tumor could be removed is through a surgery that would require the baby to be pulled out of the womb of Margaret.

"They saw something on the scan, and the doctor came in and told us that there was something seriously wrong with our baby and that she had a sacrococcygeal teratoma," Margaret said in an interview shared by Texas Children's Hospital to CNN.

"And it was very shocking and scary, because we didn't know what that long word meant or what diagnosis that would bring."

The Fetal Treatment Center said Sacrococcygeal teratoma (SCT) is more common in female babies. They are usually not malignant, but occasionally cause trouble before birth. SCTs that are largely cystic (fluid-filled) generally do not cause a problem for the fetus before birth, but SCTs that are mostly solid tissue, and has a lot of blood flow in it, can be dangerous to the fetus as it may suffer adverse effects.

"Some of these tumors can be very well-tolerated, so the fetus has it and can get born with it and we can take it out after the baby's born," said Dr. Darrell Cass, co-director of Texas Children's Fetal Center and associate professor of surgery, pediatrics and obstetrics and gynecology at Baylor College Medicine told CNN.

"But about half of the time, they cause problems for the fetus and it's usually causing problems because of a blood flow problem."

When the tumor sucks blood flow more than the heart of the baby should, complications will form and the fetus will start to get ill, as in the case of Boemer's baby.

The baby who weighed just 583 grams then was taken out of the womb for 20 minutes. After the life-saving surgery, Margaret was able to carry her baby for another 12 weeks. And finally on June 6, at 36 weeks and five days, Lynlee was born at 5 lbs, 5 oz, People reported.

Meanwhile, eight days after being born, Lynlee had another surgery to remove the remaining parts of the tumor.
