There are several hypotheses have been invoked to explain how alcohol consumption can increase the risk of cancer. It still needs further research, but at least there are some things that are considered to explain the influence of alcohol on cancer incidence.
The first is caused by the metabolic product acetaldehyde. Acetaldehyde can cause damage to DNA and cells in the body do not want to repair the damage. Acetaldehyde also trigger growth in excess of normal liver cells, and cells of this new mutation in the genes that become cancerous.
In addition, alcohol also can trigger cancer by direct contact with the organs of the body, by irritating to epithelial or increase the penetration of carcinogenic compounds into the body through the mucosa. This is because alcohol is a good solvent so that it can increase the solubility of other compounds or enhance the permeability (ease for permeable) of the mucosal layer of the mouth. In addition, alcohol also reduces salivation, thereby reducing the effect of cleaning the mouth and causing carcinogenic compounds can accumulate in the oral cavity.
The third, most alcoholic drinks also contain other compounds that are carcinogens, like nitrosamines, aromatic hydrocarbons polisiklik, mikotoksin, esters, phenols, and other compounds produced in the production process.
Fourth, alcohol has the effect of systemic (throughout the body) and locally. Has been well known that alcoholics often experience malnutrition and liver dysfunction. In fact, the liver is the organ that is essential to metabolize the drug or any other carcinogenic compounds. In addition, alcohol also has the effect of suppression of the immune system (immunosupresive) that will lower immune to cancer or cancer-causing viruses. Alcohol itself also cause liver cirrhosis which may develop into liver cancer.
Cancer is only one type of disease caused by the consumption of alcoholic beverages. Still very many more types of diseases
caused by alcohol. Danger Book and How to Overcome Alcohol addiction recently published by Elex Media Gramedia publishing group, thorough scientific review and disclose the results of the study the researchers and experts.
