Yes, alcohol consumption is associated with an increased risk of cancer, particularly breast cancer. This is due to alcohol's effects on cells, including changes in gene expression and DNA methylation. Consuming 10 grams of alcohol per day (about one beer in the US) can lead to a 4-13% increase in the risk of cancer, especially breast cancer. However, consuming folate and B vitamins like B12 might partially offset some of this increased risk, but it's not a guarantee.
