Community Meeting Addresses Rare Childhood Cancer in Orange County
On Tuesday evening, many residents of Orange County gathered for a community meeting to discuss a troubling rise in a very rare type of childhood cancer, Ewing sarcoma. Several children from the area have been diagnosed in recent years, leading to growing concerns among families.
Last week, Orange County Supervisor Katrina Foley reached out to the Director of California’s Department of Public Health, Dr. Erica Pan. In her letter, she urged the department to speed up its examination of the reported Ewing sarcoma cases in the Ladera Ranch neighborhood.
According to Foley’s office, six children in Ladera Ranch, a community of about 26,000 residents, have been diagnosed with this uncommon cancer, which mainly affects young people. This alarming number has raised significant worries among local families.
Some community members suspect the cause might be linked to an herbicide used in the area. Brian Dalton, whose daughter Lily spent a lot of time in Ladera Ranch, shared his thoughts. Lily, who passed away in January from a rare soft tissue cancer diagnosed a few years earlier, had a tumor with an Ewing sarcoma gene fusion. “This is so rare that there has to be something, and if it’s not pesticides, then what is it?” Dalton questioned.
Foley noted that the Orange County Health Care Agency had previously asked the California Cancer Registry to look into the situation back in 2024, but no clear pattern of cases was found at that time. Following renewed concerns from the community, agencies including the California Cancer Registry and UCI’s Cancer Center have been asked to reassess the situation, with results still pending.
“Ladera Ranch families deserve answers and transparency from the state,” Foley said. “We do not yet know what caused these cancers, but uncertainty calls for a thorough review of possible environmental factors.”
The California Cancer Registry stated that its assessment aims to see if the number of cancer cases in the area is higher than what would typically be expected.
A spokesperson for the California Department of Public Health mentioned the rarity of Ewing sarcoma makes it difficult to draw conclusions about potential environmental causes.
During the community meeting, the Ladera Ranch Civic Council planned to discuss “Community Health Concerns,” which includes a proposal to ban herbicides in the area.
Edward Kim, an oncologist not involved in the study, mentioned that sometimes clusters of cancer cases happen purely by chance. He emphasized that such occurrences can still fit within national averages.
Epidemiologist Logan Spector, who studies childhood cancers, noted he had already been contacted by families from Ladera Ranch. “While some environmental factors can lead to childhood cancers, Ewing sarcoma isn’t really one of them,” he clarified, adding that ancestry is a significant risk factor for this type of cancer.
U.S. Attorney Bill Essayli has also voiced his concerns, urging the Environmental Protection Agency to investigate any environmental factors that might be behind this cluster of cancer cases.
