Threshold in Carcinogenicity of Genotoxic Carcinogens [PDF]
Journal of Carcinogenesis & Mutagenesis, 2014 Nowadays the idea of threshold in the carcinogenicity of chemical carcinogens has attracted interest in the field of carcinogenesis. With genotoxic agents there is considerable experimental evidence in support of the idea. Here, we report on the low dose carcinogenicity in rats observed with heterocyclic amines contained in cooked food, 2-amino-3,8 ...

New Marker of Colon Cancer Risk Associated with Heme Intake: 1,4-Dihydroxynonane Mercapturic Acid [PDF]
, 2006 Background: Red meat consumption is associated with an increased risk of colon cancer. Animal studies show that heme, found in red meat, promotes preneoplastic lesions in the colon, probably due to the oxidative properties of this compound.

The Carcinogenicity of Chromium [PDF]
Environmental Health Perspectives, 1981 The carcinogenicity of chromium compounds is reviewed with specific attention to the gaps in knowledge for risk estimation and research needs. The most important problems at present are whether trivalent chromium compounds cause cancer, and whether there is a difference in cancer causing effects between the soluble and the slightly soluble hexavalent ...

Chemoprevention of aberrant crypt foci in the colon of rats by dietary onion [PDF]
, 2007 Onion intake might reduce the risk of colorectal cancer, according to epidemiology. However, Femia showed in 2003 that diets with a 20% onion intake increase carcinogenesis in rats. We speculated this dose was too high.
