The number of people under 50 being diagnosed with cancer has risen dramatically in recent decades. Many cases cannot be explained by a family history of disease or any lifestyle factors—such as smoking, drinking or unhealthy foods—that would otherwise put the individuals at a higher risk. Explaining this rise in early-onset cancer has therefore presented a conundrum. But clues are now emerging—is there some kind of exposure in the environment that could perhaps explain some of the cases?
