Alcohol abuse can lead to high blood pressure, increased risk of stroke and coronary heart disease, and long-term alcohol abuse can also increase the incidence of stomach, esophageal and liver cancer, while recent studies by the World Health Organization show that alcohol abuse can also lead to breast, bladder and colon cancers. The Danish brewery once stipulated that workers could drink 2 liters of beer for free at work every day, which resulted in workers in the brewery suffering from esophageal, throat, liver and lung cancers many times higher than the general population. Studies in the UK have concluded that a daily intake of 8 grams of alcohol will increase a woman’s chances of developing breast cancer by about 6 percent, and in developed countries the proportion of breast cancer caused by alcohol is about 4 percent. Studies in the United States point out that people who quote a lot of liquor and beer have more than twice the risk of colon cancer than those who abstain from drinking. What is it about the glass that makes it a human killer? Alcohol, i.e. ethanol, causes esophageal cancer, stomach cancer and liver cancer, which are often easier to understand because alcoholic beverages themselves have a strong stimulating effect on mucosal epithelial cells, which can lead to destruction of mucosal epithelium and ulcer formation; alcohol also causes damage to the function of the gastrointestinal tract, leading to abnormal gastric acid secretion or reflux esophagitis, which are all precancerous lesions; and after alcohol is absorbed, it directly enters the liver, leading to liver cell After alcohol is absorbed, it directly enters the liver and causes liver cells to mutate and cause cancer. So, through what channels does alcohol cause bladder cancer, colon cancer and even breast cancer? Let’s look at an animal test in which scientists injected cancer cells into normal mice to try to get them to transfer to the lungs, but the cancer cells were often destroyed by the immune system because of the mice’s own immunity. However, if the mice were injected with an excessive amount of alcohol first, followed by the cancer cells, then the chance of the cancer cells entering the lungs was greatly increased, reaching 40 times higher than in normal mice. It was found that alcohol can inhibit the vitality of the immune system in the body. The immune system is like the body’s defense force, once its function is inhibited, it cannot identify and kill the tumor cells in the body, and the tumor cells can easily grow up and become tumors. In addition, alcohol is a special substance, which can be dissolved in both water and oil. Therefore, alcohol can be used as a solvent to dissolve carcinogenic substances and enhance the ability of carcinogenic compounds to penetrate into mucous membranes. For example, carcinogenic substances in tobacco can be dissolved in alcohol to directly lead to the destruction of cell membranes, so smoking while drinking will greatly increase the chance of causing cancer. It can be seen that alcohol can increase the carcinogenic effect of carcinogens on the one hand, and reduce the immune ability of the body on the other. Long-term alcohol abuse will certainly lead to the occurrence of tumors. Therefore, excessive alcohol consumption is very harmful to the body, and moderate drinking should be promoted.
