Doctors puzzled after Texas girl's inoperable brain tumor disappears

The story of an 11-year-old girl and a seemingly disappearing brain tumor is sweeping the internet.

According to a GoFundMe page and website created by family members, Roxli Doss of Hays County, Texas, was diagnosed with an inoperable brain tumor in June.

"She had headaches for a couple weeks and was feeling sick," read the family's description on Roxli's GoFundMe page, which has raised more than $25,000 since it was created to help with medical expenses in June. "They went in for an MRI after numerous doctors visits and got a call sending them to Dell Children's hospital."

Doctors called Roxli's tumor a Pontine tumor, or DIPG, saying the tumor, which was on the back of Roxli's brain, pushing on her spinal cord, was inoperable.

In September, multiple posts on both websites confirmed that a Sept. 7 MRI no longer showed the tumor. Multiple news outlets shared the news, which was called "miraculous," and quickly took the internet by a storm.

According to USA Today and a statement from the family, doctors can't explain why the tumor disappeared. Although the tumor no longer threatens Roxli's life, doctors and family members are still cautious.

"This form of cancer is aggressive and grows so quickly, so the doctors are recommending a follow-up treatment to keep any cancer cells that can’t be seen from ever growing," family wrote on the website used to share Roxli's progress.

USA Today reported that doctors are watching Roxli, who will undergo immunotherapy treatments, closely.
