“They did a few tests and the mass was found,” Tanya Tucker of Joliet, Owen’s aunt, said.
The mass turned out to be a neuroblastoma.
According to the Mayo Clinic website, a neuroblastoma is a type of cancer cancer that most commonly found in children ages 5 or younger.
It develops develops from immature nerve cells, most commonly either in or around the adrenal glands, the website said.
However, "neuroblastomas can also develop in other areas of the abdomen and in the chest, neck and near the spine," the website also said.
That same night, Owen was transferred to the Ann & Robert H. Lurie Children's Hospital of Chicago where he had more tests.
By now, Owen was also dehydrated and unable to move his bowels, the GofundMe page said.
More tests revealed more tumors, Tucker said. The tumor behind Owen’s right eye had caused the swelling; he also has spot on his liver, the GoFundMe page said.
Everyone is devastated.
“He was always a happy and smiling baby,” Tucker said.
