The village of Buffalo Grove opposed the Hauber family’s application for the maximum pension and still could appeal in court. In documents and testimony in the case, the village pointed to other studies challenging theories that firefighters are more vulnerable to colon cancer than the general population. In suburban departments such as Buffalo Grove’s, the majority of calls are for medical service. Structure fires are rare. Medical reports indicate Hauber was in generally good health prior to his diagnosis and was not known to have been exposed to toxic chemicals or carcinogens on the job.
