Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Question:
We need to identify which organ's cancer risk is specifically raised in workers exposed to industrial dyes.
Step 2: Key Formula or Approach:
Certain chemicals used in the dye industry, particularly aromatic amines such as benzidine and beta-naphthylamine, are well established occupational carcinogens that are absorbed, processed by the body, and then concentrated in one particular organ before being excreted, exposing that organ's lining to prolonged chemical irritation.
Step 3: Detailed Explanation:
Aromatic amines used in dye manufacturing are absorbed into the bloodstream, metabolized by the liver, and then excreted through the urine, where they come into prolonged contact with the lining of the urinary bladder. This repeated exposure to carcinogenic breakdown products is why bladder cancer is the classically recognized occupational malignancy in dye industry workers, well documented in occupational health and epidemiological studies.
Kidney cancer is not the specific classical association with dye industry exposure, since the carcinogens act mainly on the bladder urothelium rather than the kidney tissue itself.
Prostate cancer does not have this specific well established occupational link to dye industry chemical exposure.
Lung cancer is more classically linked to other occupational exposures, such as asbestos or certain industrial dusts, rather than to dye industry aromatic amines, which act primarily on the urinary tract.
Step 4: Final Answer:
So persons working in the dye industry are prone to develop malignancy of the urinary bladder.
