“It starts right away, he had surgery the next morning to place a port in his chest, we started chemo that night, so maybe 36 hours after we’ve been with our pediatrician we were starting his first round of chemo and it jut doesn’t stop from there,” says Aiden’s mother, Erica Snyder.

Instead of starting kindergarten last year, 5 year-old Aiden, started his journey battling cancer.

“And you thought you know, it would never happen to you and then it does and it shakes up your whole world,” says Snyder.

“So we found out the next week that he had something call Philadelphia Positive Leukemia, which is something only seen in 3% of pediatric patients.”

The most common types of pediatric cancers are brain tumors, lymphoma, neuroblastoma, and retinoblastoma, but leading that list is leukemia which Dr. Kenneth Heym, a pediatric oncologist at Cook Children’s Medical Center says represents about 25% of all childhood cancer.

“Being our most common disease, the one we have the most experience with, we’ve made incredible progress in it, with very good cure rates, majority of children being cured,” says Kenneth Heym.

“Especially with Leukemia, I’ve heard of parents that would go weeks without a diagnoses because it’s an invisible sickness for a long time,” says Sndyer.

“Other than bruises on a 4 year-old boy, which I don’t know a 4 year-old boy not covered in bruises, there’s not many outward signs for a while.”

“One of the things we tell families is we can tell them a lot about the cancer that their child had, but for the vast majority of children, the one thing we can’t tell them is why it happened to their child,” says Heym.

“Cancer is genetic. It’s a problem that happens in the genes when you get mutations and cells start growing abnormally, but for most kids we don’t understand why it specifically happens to them. It’s just what we would call sporadic or out-of-the-blue or unfortunately just bad luck.”

Luckily after 29 days, treatment started working for Aiden, he’s in remission and starts Kindergarten this year.
