  CARCINOGENICITY
  Inorganic arsenic compounds are known to be human carcinogens based on sufficient 
  evidence of carcinogenicity in humans (IARC 1987).
  Many cases of skin cancer have been 
  reported among people exposed to arsenic through medical treatment with inorganic trivalent
  arsenic compounds. In some instances, skin cancers have occurred in combination with other 
  cancers, such as liver angiosarcoma, intestinal and urinary bladder cancers, and meningioma.
  Epidemiological studies of cancer after medical treatment with arsenic have shown an excess of 
  skin cancers, but no clear association with other cancers has been obtained. No relation was 
  found between prostatic cancer and treatment of syphilis with arsenicals. An association between 
  environmental exposure to arsenic through drinking water and skin cancer has been observed and 
  confirmed. Epidemiological studies in areas where drinking water
