Acetaldehyde from alcohol and mouth (oral) cancer risk
Dissecting the role of acetaldehyde in oral carcinogenesis
This research looks at how acetaldehyde — the chemical formed when alcohol is broken down in the mouth — damages DNA in oral cells and may raise the risk of mouth cancer in adults who drink.

What this research studies
If you join, researchers will collect mouth cell samples and blood from adult volunteers to measure specific DNA changes called acetaldehyde-derived adducts after alcohol exposure. They will compare damage in the mouth versus blood to understand how much comes from local oral metabolism and the oral microbiome. The team will also examine genetic factors that affect acetaldehyde detoxification and DNA repair, such as ALDH2 differences and Fanconi Anemia–related repair defects, to identify who is most vulnerable. Laboratory analyses and group comparisons will be used to trace how acetaldehyde-related DNA damage could lead to oral cancer.
Who could benefit from this research
Good fit: Adults aged 21 and older who drink alcohol — including moderate or heavy drinkers and people with known ALDH2 differences or DNA-repair disorders — would be the most relevant candidates.
Not a fit: People who do not drink alcohol, whose cancers are unrelated to alcohol exposure, or who need immediate cancer treatment are unlikely to receive direct benefit from this work.
Why it matters
Potential benefit: If successful, the work could help develop better prevention strategies, identify people at higher risk from alcohol, and guide earlier screening for oral cancer.
How similar studies have performed: Previous volunteer studies have shown a direct, dose-dependent link between alcohol intake and acetaldehyde-related DNA damage in the mouth, but applying these findings to prevention and care is still new.
