A Massachusetts high school is under investigation after “several” teachers have been diagnosed with breast cancer or precancerous conditions.

The state Department of Public Health is set to visit Uxbridge High School on Thursday to “conduct a series of air quality tests,” to determine whether the multiple cases are potentially connected.

Superintendent David Ljungberg and Principal Michael Rubin alerted families and district staff on Monday of the “sombering news,” after Uxbridge High School’s graduation over the weekend.

“We are writing to inform you about a concern we are investigating at Uxbridge High School,” Ljungberg and Rubin stated in the letter. “Several female teachers have been diagnosed with breast cancer or precancerous conditions over the past few years.”

“It is, of course, possible that these multiple cases are not connected to one another,” the leaders added, “but out of abundance of caution, we are looking into any environmental factors at the school that may be a factor in their diagnoses.”

The 123,000-square-foot school, with an enrollment of roughly 600, was constructed in 2012 at a cost of $45 million, including a $22-million state reimbursement.

Uxbridge school leaders say they notified the state Department of Health and local health board as soon as they became aware of the cases, seeking “counsel about how best to proceed.”

“Massachusetts DPH officials have indicated that there is no evidence of immediate danger in the building and no reason to limit access to or use of the facility at this time,” they wrote in their letter. “In fact, the public health officials have commended our decision to approach them with these concerns, our readiness to partner with them in support of the evaluation process.”

Health officials are assessing the school’s interior and exterior to “ensure there are no issues with the infrastructure that would present risks (including electrical, plumbing, mechanical, HVAC, and other systems)” and the indoor and outdoor air quality on campus.

The superintendent and principal said that state officials have ruled out water supply as a “risk factor” after “thorough testing.”

“The team has reached out to the women who have been diagnosed, requesting data to evaluate whether there may be a connection among their cases,” Ljungberg and Rubin wrote. “We are grateful for their cooperation.”

They added that the state has said discovering an environmental “smoking gun” is “rare” in workplace investigations.

“However, even if a direct causal link is not established,” the leaders wrote, “the administration is utilizing this process to rigorously test the building and guarantee that it meets all safety standards moving forward.”
