Cancer Risk Factor – Alcohol

Alcohol is a brain toxin and a carcinogen linked with several types of cancer, including: head and neck, esophageal, liver, breast, colorectal, etc. Ethanol breaks down to acetaldehyde, a substances that damages DNA and proteins. Alcohol also generates reactive oxygen species that also damage DNA, proteins, and fats through oxidation. It impairs ability of body to absorb a variety of nutrients and increases levels of estrogen in the blood. People often ask, “How much alcohol can I drink safely?” News releases recently have stated that ingesting any amount of alcohol increases one’s risk for cancer. Also be aware that when tobacco and alcohol are used together, the risk rises higher than either one separately. Prevention strategy? Carefully assess how much risk you are willing to take.
