Alcoholic drink benefits and risks of consuming alcohol in moderation." Alcoholic drinks are classified by the International Agency for Research on Cancer (IARC) as a Group 1 carcinogen (carcinogenic to humans). IARC classifies alcoholic drink consumption as a cause of female breast, colorectum, larynx, liver, esophagus, oral cavity, and pharynx cancers; and as a probable cause of pancreatic cancer. In the alcoholic drinks industry, congeners are substances produced during fermentation. These substances include small amounts of chemicals such as occasionally desired other alcohols, like propanol and 3-methyl-1-butanol, but also compounds that are never desired such as acetone, acetaldehyde and glycols. Congeners are
