ScienceDaily (Oct. 30, 2008) — There may be a silver -- and healthy -- lining to the miserable cloud of allergy symptoms: Sneezing, coughing, tearing and itching just may help prevent cancer -- particularly colon, skin, bladder, mouth, throat, uterus and cervix, lung and gastrointestinal tract cancer, according to a new Cornell study.
These cancers, interestingly, involve organs that "interface directly with the external environment," said Paul Sherman, Cornell professor of neurobiology and behavior, who led the study. He and colleagues analyzed 646 studies on allergies and cancers published over the past 50 years, putting together "the most comprehensive database yet available" on allergies and cancers.
The study revealed "a strong relationship" between allergies and cancer in environmentally exposed tissues, Sherman said. This relationship seldom exists, he noted, between allergies and cancers of tissues that are not directly exposed to the environment, such as cancers of the breast and prostate, as well as myelocytic leukemia and myeloma.
