Fire Departments Who Rely on OneTest™

Fire Departments Across the Nation Choose to Screen for Cancer with OneTest™ for Cancer

Why Firefighters Should Test for Cancer?

Studies by the National Institute of Occupational Safety & Health and others conclude that firefighters have a greater number of cancer diagnoses and cancer-related deaths than the general U.S. population. This includes cancers of the lung, prostate and colon, respiratory and digestive tract.

OneTest™, as part of an annual check-up, is intended to aid in the detection of multiple cancers at earlier, more treatable stages.
