For some people, esophageal cancer sends up a red flag.
Literally: it's red.
Doctors at the National Institute on Alcohol Abuse and Alcoholism report that when alcohol consumption results in facial flushing, it's time to call your M.D. to schedule an endoscopic cancer screening.
Research shows that an inherited deficiency in an enzyme known as ALDH-2 prompts facial flushing after just a couple of drinks. And this warning sign suggests a much higher risk of esophageal cancer compared to the general population.
NIAAA officials estimate that well over 500 million people worldwide may be deficient in ALDH-2. And it appears that every one of them who also drinks alcohol may also be raising their esophageal cancer risk.
Esophageal cancer is one of the deadliest, with a very low 5-year survival rate
