Allergies linked to lower incidence of brain cancer in the study

T The study does demonstrate a cause and effect, such as allergies directly reduce the risk of brain cancer. Only shows a possible link, what doesn t swing Dr. Eugene S. Flamm, chairman of the department of neurosurgery at Montefiore Medical Center in New YorkIn the study, published Feb. 7 in the journal Cancer Epidemiology, Biomarkers & Prevention, McCarthy and his colleagues reviewed surveys completed by 419 patients with glioma and 612 cancer-free patients in North Carolina and Illinois. All patients were asked if they had physician-diagnosed seasonal allergies, medications, food, pets or others and if they have taken antihistamines.

If you have allergies, courage: Researchers say it may be less likely to develop a hard to treat brain cancer, probably because the immune system is on alert.

It is not clear how this knowledge can improve the prevention or treatment of brain cancer, but study author said the findings open the way s to new research.

With short rural Australia 17,000 health professionals, we hope that the infrastructure improvements will attract more doctors and nurses in the bush.

You can not tell people to go out and develop allergies. That will not happen. And you can t tell people with allergies who is doing a good thing, and don t try to get rid of them.

Researchers have published conflicting studies that people with allergies and autoimmune diseases have a lower risk of developing cancer, said McCarthy. We wanted to see the range and see if we have found an association with any type of allergy, said McCarthy.

We must do more studies to really what the underlying mechanism. Then we might be able to do things that might influence people who may have a higher risk, or perhaps a family, said Bridget J. McCarthy, a research associate professor of epidemiology at the University of Illinois at Chicago.

The lesions studied are known as gliomas, the most common type of brain tumor in adults. They represent more than half of malignant brain tumors, more than 18,000 diagnosed in the United States each year, according to the National Institute of Cancer.

One of the reasons for the conflicting reports, the authors, is that the allergy has been defined differently in different studies, sometimes a lot, sometimes narrow, as seasonal allergies alone. Further studies are needed, they said.

As the authors point out, there are several conflicting reports in the literature, and this article does not help in any way, Flamm said.

The researchers found that patients with high and low grade tumors are more likely to report than other patients without allergies. And more than anyone had allergies, the probability of gliomas.

Antihistamine use didn t affect the results, according to the authors.
