Study: People with Allergies, Asthma, and Eczema Suffer Fewer Brain Cancers


Let’s face it: there are very few occasions to rejoice at having respiratory allergies, asthma or eczema, but here’s one: reduced chance of developing brain cancer.

The study, published in Cancer Epidemiology, Biomarkers & Prevention, was conducted by an international consortium of researchers from five countries led by researchers from the Dan L Duncan Comprehensive Cancer Center at Baylor College of Medicine.

They analyzed the health data of 4,533 patients who had glioma – a type of brain cancer – to 4,171 people without brain cancer. The researchers found that a history of asthma, respiratory allergies or eczema was associated with a 30% decrease in the risk of developing glioma.

We feel it’s now time for the next steps to be taken in this research area.”

Research into the mechanism behind this association may someday lead to better prevention and treatment options for gliomas. In the meantime, those suffering with allergies, asthma, or eczema should take solace in knowing there may be a protective factor associated with their medical conditions.
