Reduced Risk of Cancer for Sufferers of Asthma and Eczema


Research published in the Annals of Allergy, Asthma & Immunology concluded that men who suffered from eczema had a lower risk of lung cancer and those having a history of asthma had a lower risk of stomach cancer. The researchers believe the hyper-reactive immune system of these sufferers may have enabled the elimination of the abnormal cells more efficiently.

Data were collected on 3,300 men ages 35 to 70 between August 1976 and March 1986 who had been diagnosed with cancer and a control group of 516 people who did not have cancer. Using group data researchers determined whether there was a link between allergies such as asthma and eczema and the incidence of eight most common types of cancer. Although they were unable to identify which factors related to asthma and eczema were responsible for reducing the risk of cancer, the findings offered new possibilities for research involving immunological and molecular mechanisms that may eventually provide opportunities for prevention.
