Bill Essayli is calling for an investigation after a number of diagnoses involving an extremely rare cancer unsettled families in an Orange County community, according to a report by the New York Post. The unusual concentration of cases has drawn the attention of federal officials in Los Angeles.

The report says Los Angeles' top federal prosecutor sent a letter Thursday to the US Environmental Protection Agency, seeking closer scrutiny of the situation. That step suggests the matter is being treated as a potential public health concern that could require environmental review.

Families in the affluent Southern California area have been rattled by the diagnoses, with questions growing about whether the cases could share a common factor. Because the cancer is described as exceptionally rare, the reported cluster has increased pressure for authorities to determine whether there is any identifiable cause.

At this stage, the available details remain limited, and no conclusions have been announced about what may be behind the cases. Still, the push for an investigation marks a significant escalation as residents seek clarity on the rare cancer diagnoses affecting the Orange County community.
