Alcohol Tobacco And Cancer

The first part of this book addresses in detail the correlations between alcohol and carcinogenicity, focusing on specific organs such as the upper aerodigestive tract, liver, colon, pancreas and breast. This includes the impairment of methionine-folate metabolism and DNA methylation by alcohol, as well as the use of s-adenosylmethionine to prevent cancer. Furthermore, the synergistic effects of reactive oxygen species and iron in producing liver cancer are addressed. The second part is dedicated to the role of tobacco in lung and digestive tract cancers and to their prevention, highlighting the role of phytochemicals. More specifically, the mutagenic, mitogenic, precarcinogenic, anti-apoptotic, and immunosuppressive properties of nicotine which are involved in the development of cancer, and the possible use of nicotine vaccine in the prevention of mortality associated with tobacco, are discussed.
