VIDEO: Inside her Tucson home, Janet Quesnel, is enjoying retirement. She spends time with her two sons and five grandchildren, but not a day goes by the she doesn't think about her late husband, Tom.
"He got very ill in the spring of 2012. It took a couple of months to really get it pinpointed as to what he had going on. Once they pinpointed it, it was leukemia," said Quesnel.
Tom battled cancer for two years. He took a step back from work and a job that he very much loved to do. "He had thought about being a firefighter all along. He thought that would be what he wanted to do from there on out," said Quesnel.
Tom worked his way up in the ranks and eventually became a Fire Cause Investigator. Even after his diagnosis, he never lost sight of his family at the Tucson Fire Department. He began researching the link between firefighting and cancer.
