A Southern California mother is raising concerns that a mysterious cancer cluster in her Orange County neighborhood may be affecting pets, in addition to the at least six children who have died from a rare form of cancer since 2013. Kira Davis, a resident of the master-planned community of Ladera Ranch, believes animals may be falling victim to the same potential environmental factors. Her suspicions were heightened after her own dog was diagnosed with a brain tumor.
"I received dozens and dozens of posts" from neighbors reporting similar pet illnesses after Davis shared her dog's diagnosis in a community chat group, she told NewsNation. Her dog developed a brain tumor and went blind.
Ladera Ranch has been grappling with an unusual number of Ewing sarcoma cases, a rare bone and soft tissue cancer that affects only an estimated 200 to 240 children and teens nationwide each year. The California Cancer Registry confirmed several cases of Ewing sarcoma in Ladera Ranch during a 10-year period ending in 2021.
Families in the community have for months urged officials to investigate potential environmental contributors to the cancer diagnoses among local children. Many have raised concerns about the possible link between years of pesticide spraying and the cluster of rare childhood cancers. Davis noted that the community is among the last in Southern California to use older, harsher chemical pesticides, while most other communities have transitioned to organic alternatives.
Another rare cancer, synovial sarcoma, which affects fewer than 1,000 Americans annually, has also been reported in Ladera Ranch.
While health officials have not yet established a connection between environmental factors and the cancer cases, multiple studies and investigations are currently underway to determine the cause. Ladera Ranch has temporarily banned the use of toxic chemical products while a local advisory committee reviews its landscaping maintenance practices. Investigations are ongoing to determine the cause of the apparent cancer cluster, and residents are pushing for a change in pesticide use, citing the possibility of a connection, however slim.
