It's important to know that there are three well-established processes of carcinogenesis initiated by alcohol consumption*: Genotoxicity Acetaldehyde can accumulate in the upper air-digestive tract (head, neck and esophagus) and colon, increasing the risk of cell damage and carcinogenic mutations.

Permeability and intestinal biota Acetaldehyde accumulation alters the enteral microbiome, which increases intestinal permeability and microbial translocation (which is when bacteria from the gut move to other parts of the body), potentially leading to inflammation and carcinogenic risks.

DNA Damage Alcohol consumption is associated with direct damage to cell DNA, causing chromosomal aberrations, the appearance of micronuclei and DNA adducts, which can initiate the process of tumor formation.

The good news is that there is evidence that these processes can be reversed by stopping or reducing alcohol consumption! By stopping drinking, the body has a chance to repair this damage. Compared to continued consumption, reducing or stopping alcohol consumption reduces the incidence of some cancers: oral cavity and esophagus: strong evidence* larynx, breast and colorectal: limited evidence*

In 2024, a Working Group of IARC reviewed scientific evidence on the effects of reducing or stopping alcohol consumption versus continuous consumption in relation to the risk of cancers of the oral cavity, pharynx, larynx, esophagus, colorectal, liver and breast:

Alcohol & Cancer Stopping drinking reverses alcohol-related carcinogenic mechanisms

Alcohol absorption: After drinking, alcohol (ethanol) is absorbed by the small intestine and enters the bloodstream.

Liver metabolism: When it reaches the liver, alcohol begins to be metabolized by the enzyme ADH, which converts ethanol into acetaldehyde. Subsequently, the ALDH enzyme transforms acetaldehyde into acetate, which is then broken down into water and CO2 for elimination.

How does alcohol beverage consumption impact cancer risk?
