Increased Risk of Certain Cancers
While many people are aware that excessive alcohol consumption is linked to liver disease, fewer know about its connection to various types of cancer. Alcohol is classified as a Group 1 carcinogen by the International Agency for Research on Cancer (IARC), and its consumption is associated with an increased risk of:
- Breast cancer: Alcohol can increase estrogen levels, which may promote the growth of hormone-receptor-positive breast cancer cells.
- Colorectal cancer: Alcohol can damage the lining of the colon and rectum, potentially leading to the development of cancerous cells.
- Oral and esophageal cancers: The metabolization of alcohol produces acetaldehyde, a toxic chemical that can damage DNA and proteins in cells, increasing the risk of cancers in the mouth, throat, and esophagus.
Moderation and awareness of these risks are key to minimizing the negative health impacts of alcohol consumption.
