A 55-year-old worker in a dye manufacturing industry presents with painless hematuria. Cystoscopy reveals transitional cell carcinoma. Which occupational exposure is most likely responsible?

• A Asbestos
• B Benzene
• C Vinyl chloride
• D Aromatic amines ✓

Explanation

Aromatic amines such as benzidine and 2-naphthylamine are well-established bladder carcinogens. Asbestos causes mesothelioma, benzene is linked to leukemia, and vinyl chloride causes angiosarcoma of the liver. Bladder cancer in a dye worker strongly points to aromatic amine exposure.
