Transcript of AP Biology Prezi
After analyzing the data, the research team found that those who had more types of allergies- to food, pollen and pets- were less likely to develop either high-grade or low-grade gliomas than those who weren’t allergic to anything. More precisely, of the 75 patients who had low-grade brain tumors, just 20 patients or 27 percent reported having any allergies while of the 612 healthy patients, 282 or 46 percent reported having any type of allergies. The more allergies you have, the more protected you were.
Also for their study, the researchers also recorded regular use of medications of the participants for two years or more before the survey, along with details of the brand, frequency, and duration of medication. The data showed that the use of antihistamines, including the potential neurocarcinogen diphenhydramine hydrochloride, was not associated with glioma risk. The study confirms that there is a relationship between the immune system of allergy sufferers and glioma risk. A comprehensive study of allergies and antihistamine use with standardized questions and biological markers is essential to further explain the biological mechanism that may be involved in brain tumor development. Glioma isn’t the first cancer to be negatively correlated with common allergies, says Michael Scheurer, an epidemiologist at Baylor College of Medicine in Houston. Allergy-prone people may fight off colorectal and pancreatic cancer, and even childhood leukemia, better than sniffles-free people, according to some studies. At the other end of the spectrum, allergies that cause asthma may spur lung tumors.

Just why these links exist isn’t clear but scientists still can hypothesize about how they coexist. Allergy sufferers mount heightened immune responses to some foreign or dangerous cells and chemicals and cancer cells are certainly dangerous. Human immune systems naturally seek them out. The immune systems in people with allergies may just do it better. Allergy-prone people have an overactive immune system, and maybe that’s been protecting them from the development of tumors. Recent studies have shown that there is a high probability that there a connection between cancer and allergies. And the basis for that connection is the immune system, our body's self-defense system. The immune system includes many different kinds of specialized cells which protect us from disease by killing foreign invaders like bacteria and parasites.
