Environmental testing has officially begun in a well-off community in Southern California, triggered by concerns over six cases of a rare cancer. This testing started on Sunday in Ladera Ranch, Orange County, as students and researchers from Cal State Fullerton collected samples from three local parks. Residents had expressed outrage after the bone and soft tissue cancer known as Ewing sarcoma affected several community members.
The researchers’ goal is to investigate any potential environmental connections to the cancer cases. “It’s very difficult to prove causation, and we don’t even know that this is environmental. It could be something else that’s potentially causing childhood cancers, but what we want to do is figure out if there is something in the environment. We can figure out if it’s here,” said Professor Daniel Curtis from the chemistry department.
Test results may be available as soon as the end of this week. Amid this situation, residents of Ladera Ranch have called on their homeowners association to halt the spraying of pesticides.
At a recent meeting of the Ladera Ranch Maintenance Corporation, numerous residents voiced their concerns about pesticide usage. One attendee was a mother who tragically lost her son to cancer earlier in the year. While there isn’t concrete evidence linking pesticides to the disease, the community’s fears have heightened due to several young people succumbing to this rare cancer.
A county-level review conducted in 2024 did not identify any unusual patterns; however, the community noted that the data was limited and requested a more “focused assessment.” Ewing sarcoma primarily affects young children and teenagers, accounting for only about 1% of childhood cancers, with approximately 225 cases reported annually. Nevertheless, the areas surrounding Ladera Ranch have seen between 9 to 12 cases of both Ewing and synovial sarcoma, resulting in six fatalities.
Among the affected was 23-year-old Lily Dalton, who passed away in January, and 17-year-old Brody Matteson, who lost his life in March. Additionally, students from USC have expressed interest in conducting their own research into the matter.
