Water-related carcinomas : Environmental classification.
Water-related cancers may be classified in four groups, which correspond closely and naturally with those used by Bradley for the classification of water-related communicable disease :
(1) waterborne cancers induced by ingestion or inhalation of carcinogens present in drinking water (for example, arsenic-induced skin and radon-induced lung cancer) ;
(2) water-washed cancers due to the use of inadequate volumes of water for personal and domestic hygiene (penile carcinoma ; gastric cancer associated with Helicobacter pylori infection) ;
(3) water-based cancers associated with helminthiases (bladder cancer due to Schistosoma haematobium infection ; colorectal cancer associated with S. japonicum (possibly also S. mansoni) infection ; bile duct cancer associated with Opisthorchis viverrini and Clonorchis sinensis infection) ;
and (4) water-related insect vector cancers associated with a water-related insect vector communicable disease (Burkitt's lymphoma when associated with malaria infection).
Caution should be exercised, however, when using such a classification : definition of a particular cancer as water related does not mean that all cases of such cancer are water related, but only that some cases may be water related.
