Parents in Ladera Ranch, California, are demanding answers after multiple children were diagnosed with rare cancers, citing concerns over pesticide use and urging local officials to investigate potential environmental links.
Residents of Ladera Ranch, an affluent Orange County community, have raised alarms after at least six children were diagnosed with Ewing sarcoma, a rare bone and soft tissue cancer that affects 200 to 240 children annually in the U.S. The cases have sparked fears of a cancer cluster, with parents and activists calling for a comprehensive investigation into possible environmental triggers, particularly the widespread use of pesticides in the area.
Community Fears and Personal Tragedies
For families like Megan Matteson’s, the crisis is deeply personal. Within days, 62 responses poured in, with some claiming multiple cases on the same street and others noting an unusual number of pets developing cancer. This is not random,
said Jessica Keetch, whose daughter, Haven, had her right foot amputated after getting diagnosed with a rare cancer called synovial sarcoma. I think people need to listen and wake up and realize something is happening to our children.

The emotional toll is palpable. Keetch described the day her daughter was diagnosed as the worst day for a parent you can ever have.
Matteson, meanwhile, recounted how three families reached out to her immediately after Brody’s diagnosis, highlighting both the support and the fear. It was helpful but scary at the same time,
she said.
Pesticide Use and Regulatory Concerns
Activists like Jackie Frentz have turned their focus to pesticide application records. Frentz, an attorney and resident, reviewed public documents and found that 17 types of pesticides and herbicides were used in Ladera Ranch during June alone, with spraying occurring almost daily. We still don’t know what is causing this, or even whether it officially qualifies as a cancer cluster,
Frentz said. But it is difficult to ignore such an unusual number of cancer cases, especially rare types.
Official Responses and Next Steps
The Orange County Health Care Agency has begun reexamining the cases in response to resident demands, though it has not confirmed a cancer cluster. We don’t know for sure what is causing this, and we don’t know if it’s an official cancer cluster yet,
said Frentz. We just know it looks highly unusual to have this much cancer, specifically rare forms of it, in our community.

As the debate continues, the community remains divided. While some urge caution, others argue that the data is inconclusive. These are our children. These are our babies,
Keetch said. I raised my children in Ladera, thinking it’s safe. Maybe there’s no safe community, but if we can do better, we need to do better.
NBC Los Angeles reported on the community’s efforts to ban toxic pesticides, while VINnews highlighted the 62 responses to Matteson’s Facebook post.
