The histopathological diagnosis of forestomach lesions and the relevance of the data for human risk estimation can be controversial. The pathological classification may be troublesome because of the low-grade malignancy and the pseudoepitheliomatous hyperplasia that may develop after ulceration and inflammation. For human risk estimation it is important to understand the mechanism of action; this is illustrated by examples using butylated hydroxyanisole, methyl bromide, and epichlorohydrin. Another feature that complicates risk estimation is the absence of a homologue for the forestomach in man. The potential risk from non-genotoxic forestomach carcinogens in man involves exposure of the mouth, pharynx, and esophagus at dose levels that exert irritating action. It is assumed that exposure to non-genotoxic chemicals at concentrations far below those having irritating potential is not hazardous to humans.<\/jats:p>","DOI":"10.1177\/019262338801600209","type":"journal-article","created":{"date-parts":[[2009,9,14]],"date-time":"2009-09-14T21:30:11Z","timestamp":1252963811000},"page":"165-171","source":"Crossref","is-referenced-by-count":28,"title":["Forestomach Carcinogens: Pathology and Relevance to Man"],"prefix":"10.1177","volume":"16","author":[{"given":"Peter W.","family":"Wester","sequence":"first","affiliation":[{"name":"National Institute of Public Health and Environmental Protection, P.O.
