A study by UC Riverside found that heating e-cigarette fluids produces toxic chemicals, methylglyoxal and acetaldehyde, which can damage human lung cells, with methylglyoxal being potentially more harmful even at lower levels, raising concerns about long-term health risks of vaping.
A doctor warns that facial flushing after drinking alcohol, caused by the buildup of toxic acetaldehyde, may indicate a higher risk of cancers such as pancreatic, stomach, and esophageal cancer, especially in individuals with certain genetic variants affecting alcohol metabolism. Genetic testing can identify susceptibility, and reducing alcohol intake or choosing lower-alcohol options may mitigate risks.
A comprehensive study reported in the New England Journal of Medicine by an international team of medical experts suggests that stopping alcohol consumption can lower the risk of developing certain types of cancers, particularly those of the mouth and esophagus. The harmful effects are attributed to acetaldehyde, a toxin produced during alcohol metabolism. The research indicates that temporary abstinence, such as going dry in January, is unlikely to significantly impact cancer risk unless the reduced consumption is sustained over a longer period.
