There is a general belief that moderate drinking lowers the risk of heart diseases since studies have shown that moderate drinkers have reported lower cardiovascular problems than heavy drinkers or complete abstainers. However, what is often ignored is a visible link between alcohol consumption and the deadly cancer. Here is a report:

1.      Liver cancer: Alcohol is one of the major causes of liver cancer. After years of heavy drinking the liver tends to do some self-repairing and in the process causes a mutation which leads to the development of cancer. The risk of liver cancer is higher in a heavy drinker who is also infected by Hepatitis B or C.

2.      Esophageal cancer: Cancer of the Esophagus is, reportedly, higher in case of regular drinkers. However, the risk gets heightened when a person indulges in both smoking and drinking.

3.      Breast Cancer: Cancer Research UK  states that the risk of breast cancer is increased by 9% for every unit of alcohol drunk everyday. Breast cancer occurs due to many factors and undoubtedly alcohol plays a key role in it. It is believed that alcohol affects breast cancer by increasing the levels of estrogen.

4.      Oral cancer: Heavy drinkers are said to be 4 times more likely to develop mouth cancer than their non-drinking counterparts. A study from the UK shows that the incidence of mouth cancer has increased by 25% over the last few years. This has been accompanied by a decline in the rate of smoking which suggests that the increase has occurred owing to alcohol consumption.

Thus, we can see that there is a direct link between alcohol consumption and various forms of cancer. Though it is not precisely known how alcohol causes cancer, there is a notion that alcohol damages DNA and, therefore, causes cancer to develop. Though a lot more research needs to be done in this field, we can safely surmise that alcohol does have a role in development of cancer and so it is best advisable to shun that sinful bottle.
