Professions at Risk

Workplace chemical exposure is responsible for an estimated 25% of all cases of bladder cancer, making it the second leading cause of bladder cancer behind smoking. Generally, aromatic amines are the chemicals responsible for an increased risk. Aromatic amides appear in the products of the dye, rubber and chemical industries, as well as in hair dyes, paint, car exhaust and more. People who work in these industries are at particular risk of bladder cancer from occupational exposure.


Modern homes and buildings contain many synthetic and plastic materials that create more smoke when burning than natural materials. When materials burn, they release a number of carcinogens (cancer-causing agents) including polycyclic aromatic hydrocarbons (PAHs), a group of more than 100 chemicals...more



Painters are exposed to a range of complex chemical mixtures which include organic solvents and dye products with known carcinogenic and mutagenic potential. Trade painters or those manufacturing paints and coatings have increased rates of non-malignant diseases and cancers; including lung cancer, acute leukemia, bladder cancer...more

Painter at Work


A number of epidemiologic studies have focused on the risk of bladder and lung cancer in hairdressers and beauticians, and the risk of breast cancer and bladder cancer associated with the private use of hair dyes has also been addressed. The most consistent, although by no means unequivocal, the finding is the increased risk of bladder cancer in male hairdressers. ...more

Road Paving

Twenty epidemiologic studies have described cancer risk in asphalt workers and roofers in various countries. A current concern for these workers is the potential carcinogenicity posed by inhalation of bitumen fumes or dermal exposure to bitumens. Bitumens are chemically different from many carcinogenic coal-tar based materials. Both have been employed in road paving and waterproofing...more

Vehicle Repair and Maintenance 

Results of epidemiological studies indicate that individuals working as truck and auto mechanics are at increased risk of bladder cancer: those who work in occupations, industries, or indicate exposure to chemicals similar to that of auto and truck mechanics are also at a higher risk of bladder cancer...more 


Machining and Metal Works

Cancer sites contributing the most attributable cases were larynx, esophagus, brain, female breast, and uterine cervix. With constant workplace MWF exposure of 0.1 mg/m3 over a 45 years working life, the risk of attributable cancer was 3.7% or, excluding the less certain female cancers, 3.1%...more

Thousands of workers are engaged in the textile industry worldwide. The textile industry involves the use of different kinds of dyes that are known to possess carcinogenic properties. Solvents used in these industries are also associated with different health-related hazards including cancer...more

Boot and Shoe Manufacturing

Early death certificate surveys showed an increased risk of bladder cancer among shoemakers and repairers. Later studies provided evidence of an increased risk associated with employment in the leather industry...more

Railroad Work

Every year, America’s railroads transport 30 million travelers to their destinations and move 1.6 billion tons of freight — food, crude oil, grain, vehicles, lumber, chemicals, crushed stone, metal ore and many other products. And every day, the railroad workers who keep the system on track are exposed to substances that put them at increased risk of developing cancer down the line...more
