Girl's brain tumor vanishes, and more medical miracles that inspired us in 2018

The apparent miraculous healing of an 11-year-old girl who was diagnosed with deadly brain cancer is one of several mysterious and inspiring medical cases from 2018.

Roxli Doss of Texas was diagnosed with an inoperable brain tumor in June known as diffuse intrinsic pontine glioma. She wasn't expected to survive. But, weeks later, the tumor vanished from MRI scans, her family said. Doctors have no explanation.

"God healed Roxli," her mom Gena Doss said.

Today, Roxli is "just as active as she ever was," her dad Scott Doss said. She's even horseback riding.

Here are more shocking health stories from the year:

Boy comes back to life after parents sign organ donation papers

The day before doctors were set to pull the plug on 13-year-old Trenton McKinley's life support systems, the boy started showing signs of mental cognition. He was so close to death, his parents had signed papers to donate his organs to five separate children needing transplants. Trenton had been flipped in a cart while being pulled by a utility vehicle. At the hospital, he "died 4 times (and) one time for 15 min. The last time they brought him back he had no brain waves," his mom Jennifer Nicole Reindl wrote on Facebook. The only explanation for his sudden recovery? "It's a miracle," she said.

Dog sniffs out owner's ovarian cancer — three times

An emergency room doctor told Stephanie Herfel she had an ovarian cyst and sent her home with narcotic pain meds. But Herfel's dog nervously sniffing her lower belly and then hiding prompted her to get a second opinion — one that revealed she actually had ovarian cancer. Since then, The Siberian husky, Sierra, later identified Herfel's cancer twice more, again in 2015 and then in 2016, by sniffing and hiding. Now, Herfel is cancer-free and raising funds for research on ovarian cancer.

Stephanie Herfel relaxes with her Siberian husky, Sierra. The dog's nose detected a scent in Herfel's abdomen that was diagnosed to be ovarian cancer. Sierra acted strangely on two subsequent occasions, and both turned out to be reccurrences of cancer.
