Drinkers Beware: Face Flushing Sign of Cancer Risk
If your face gets flushed when you drink alcohol, you could be in danger of developing esophageal cancer.
Researchers said facial flushing after drinking is predominately caused by an inherited deficiency in an enzyme called aldehyde dehydrogenase 2, or ALDH2. There is growing evidence that ALDH2-deficient people are at a much higher risk of esophageal cancer, specifically squamous cell carcinoma, from alcohol consumption than those individuals with fully active ALDH-2.
There are about 540 million ALDH-2-deficient patients in the world, so even a small percent reduction in esophageal cancers due to a reduction in alcohol drinking would translate into a substantial number of lives saved, researchers said.
Esophageal cancer is one of the deadliest cancers, with five-year survival rates of 15.6 percent in the United States, 12.3 percent in Europe and 31.6 percent in Japan. Nearly one third of East Asians experience facial flushing, nausea and an increased heart rate after drinking alcohol.
