Lily Walker’s parents had expected to watch their daughter run track and cross country at Haverford High School. Instead, in eighth grade, she suddenly lost weight and suffered severe headaches.  

Peter Cellucci’s parents hoped to see him on a Malvern soccer field. Instead, the then-seven-year-old stopped eating and was losing his balance.  

The two second cousins live 17 miles apart and both were diagnosed with brain tumors. 

It gave medical experts pause and tested the endurance of the family’s Catholic faith, writes Wendy Ruderman for The Philadelphia Inquirer. 

Pediatric cancer is rare. Malignant brain tumors in kids are rarer still.  

Both are continuing treatment to keep the tumors stable.  

Lily, now a Haverford High senior, shares her experience with area students, handing out bracelets that read, “Lilly Strong.”  

NFL Quarterback Carson Wentz, who met Lily while he was with the Eagles, wears it during games. 

“I love to talk to people and spread my message, ‘Be happy. Just be happy,’” she said. 

Peter, a third grader at St. Patrick’s School in Malvern, still struggles to eat. 

Tricia Cellucci said she reminds herself that he’ll have more healthy days than sick ones. 

“And today,” she said, “is a good day.”
