At 17 months old, Olivia Gregg was diagnosed with stage 4 retinoblastoma cancer.
According to Los Angeles Children's Hospital, the cancer can start growing at any time before birth up until about 3 years of age. Occasionally, it is not detected until ages 7or 8.
"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.
But 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 is an indicator of 15 different eye cancers and diseases, according to L.A. Children's Hospital.
Nar now wants to share Olivia's story with other parents.
She's raising money to fight childhood cancer in a "HopeKids" walk in September.
