A white glow around a child's eye in a picture could be a strong indicator of cancer or other diseases.
At 17 months old, Olivia Gregg was diagnosed with Stage 4 Retinoblastoma cancer.
According to L.A. Children's Hospital, the cancer can start growing at any time before birth up until about three years of age. Occasionally, it is not detected until ages seven or eight.
"March 20, 2012 was the worst day of my life," said Olivia's mom Nar. "I just remember the doctor walked in the room, Olivia was sleeping in my lap and he said she has cancer."
The fight was long and ugly. For six months, Olivia went through chemotherapy and various other types of treatment.
Olivia's cancer could have been diagnosed earlier from a picture taken from her first birthday. It shows a white ring around her eye.
"I thought it was just a defect, I tried red eye reduction and it didn't work so I just deleted it," said Nar.
The white glow though, was actually the flash of the camera reflecting off the cancerous tumor in Olivia's eye.
One in 80 children will have the glow. The glow can be an indicator of 15 different eye cancers and diseases, according to L.A. Children's Hospital.
Nara now wants to share Olivia's story with other parents. She's raising money to fight childhood cancer in the "HopeKids" walk in September.
