A state health official says the state is monitoring after a study found a cluster of cases of a rare form of a pediatric cancer in southeastern New Hampshire.
State Epidemiologist Dr. Benjamin Chan says they didn't find any behavioral or environmental risk factors deemed a contributor to the "small excess number of cases."
The report published last month was launched after a child in Rye was diagnosed in early 2014. The study found less than five cases in the area over a decade. That's still higher than average. The study didn't indicate a link.
Chan says he hopes the community is reassured because there haven't been any connections to any widespread contamination.
The state plans to re-evaluate the number of cancer cases in 2017.
