Ladera Ranch Families Call for Answers Amid Growing Childhood Cancer Concerns

When the California Cancer Registry released its latest figures on Ewing sarcoma, a handful of parents in the upscale Orange County community of Ladera Ranch felt a familiar chill. The numbers—fewer than 11 cases over a ten‑year span ending in 2021—were already old, and several diagnoses that surfaced after that date weren’t reflected at all.

Take 17‑year‑old Brody Matteson, who passed away in March 2026 after a painful battle with the bone‑and‑soft‑tissue cancer. Or 23‑year‑old Lily Dalton, who died earlier this year. Their families, like many others, have been pushing local officials for a clear picture of what’s happening, and the newest data only seem to deepen the mystery.

“Has that number grown?” Orange County Supervisor Katrina Foley asked on CBS, her tone a mix of frustration and urgency. “If it’s grown enough to be a cause for alarm, we need answers now so we can protect public health.” Foley has repeatedly asked for a simple map showing where each of the 35 reported cases in the county occurred, yet the request has gone unanswered.

For the residents, the unanswered questions are more than academic. They point to decades of pesticide and herbicide applications across the master‑planned community—spraying that, they argue, could be a silent culprit behind an unsettling cluster of rare cancers.

“Why are so many young children and adults developing incredibly rare cancers in the same community?” asked Brian Dalton, father of Lily. His question echoes through the neighborhood, where neighbors recall seeing kids playing on bike jumps and at parks just weeks before a diagnosis was confirmed.

Health officials maintain that no direct link has been established. The American Cancer Society notes that Ewing sarcoma strikes roughly 200 to 240 children and teens nationwide each year—a rarity by any measure. Yet the clustering of cases in a relatively small, affluent suburb feels too close for comfort.

Adding to the pressure, federal eyes have turned toward Ladera Ranch. First Assistant U.S. Attorney Bill Essayli wrote to EPA Administrator Lee Zeldin, requesting a review of whether environmental regulations might have been breached and if an EPA investigation is warranted.

Local law firm Bond Legal has also opened its own probe, seeking records from families whose children lived in or frequently visited Ladera Ranch and were diagnosed with either Ewing sarcoma or other rare tumors such as synovial sarcoma—another cancer that claimed 18‑year‑old Haven Keetch’s leg.

Investigators plan to scrutinize historic pesticide and herbicide usage, soil and groundwater conditions, and even the area’s former agricultural past. Until those studies are completed, the community’s fear remains palpable, a mix of grief, anger, and a yearning for transparency.

“It seems like an unreal number of kids sick,” said resident Karen Smith to CBS. “We want to know what the true cause is.” For now, the answers lie somewhere in the data that has yet to be fully gathered and interpreted.
