A simple photograph is all it takes.

A woman was looking at her son and noticed that his eye looked a little off. She decided to do a little research and found some videos about what she saw. They led her to how to detect eye cancer in children.

Then she did what the video said and took a picture of her son and found out that his eyes weren't the same color in the photo. When she took him to the doctor they found out he had retinoblastoma and that 75 percent of his eye was covered in tumors.

Thankfully, they caught it in time and they were able to get the eye out, but now she wants other parents to know about this and possible save other children's lives. In the mean time her son will be tested for a genetic marker, which would mean he could get other kinds of cancer in the future.
