At fire house 12 in Waipahu, firefighters aren't just worried about their own health. They're worrying about their kids. In the last five years, children of three firefighters at the station have been diagnosed with bone cancer.
The third case was diagnosed this month.
In the wake of the cancer cluster, Honolulu's fire chief and the firefighters union are calling for an investigation.
"It's startling," said Capt. Andrew Fukuda, who's assigned to the Waipahu fire house.
"This is not really a coincidence. When it happens three times at the same station to our firefighters' children, everybody's concerned. Everybody's concerned about it."
The first diagnosis came in June 2013. Sky Racoma, 4, was diagnosed with Ewing's sarcoma, a rare type of bone cancer. She is now in remission.
