Exhaust fumes linked to bladder cancer

Lorry drivers and other workers exposed regularly to vehicle exhaust fumes are at greater risk of contracting bladder cancer, a US study found. Researchers investigated about 2,000 cases of bladder cancer in men and attempted to identify associations with their work. “Our findings indicated that males usually employed as truck drivers or deliverymen have a statistically significant, 50 per cent increase in risk of bladder cancer,” the study found. “Overall, a statistically significant trend in risk with increasing duration of truck driving was observed. This trend was particularly consistent for drivers first employed at least 50 years prior to diagnosis. Of these, truck drivers employed 25 years or more experienced a 120 per cent increase in risk. Elevations in risk were also suggested for taxicab and bus drivers.” In June 2012, IARC rated diesel exhaust fume as a group 1 human carcinogen.
