Alcohol causes cancer.
Alcohol is classified as a class I carcinogen by the International Agency for Research on Cancer of the World Health Organization, and a class I carcinogen means sufficient evidence of carcinogenicity to humans, so alcohol can cause cancer is clear. And according to clinical studies, drinking alcohol can directly lead to irreversible mutations in hepatocyte genes, and it was found that alcohol and its metabolite acetaldehyde can have a significant impact on hematopoietic stem cells.
In clinical diagnosis and treatment, it is found that a variety of diseases are related to alcohol consumption, such as liver cancer, esophageal cancer, colorectal cancer, gastric cancer and many other cancers are closely related to alcohol consumption. The biological mechanism of alcohol carcinogenesis has been elucidated, mainly because the metabolite of alcohol, acetaldehyde, can damage the DNA of liver cells, which leads to malignant cell proliferation.
To summarize, alcohol can cause cancer, it is recommended that we try not to drink alcohol, and must maintain good dietary habits to prevent diseases.
