@ca There are actually some apparent results in the literature to the contrary — but this certainly wouldn't be the first study to report a negative correlation between #atopy (including #allergic #rhinitis and #atopic #dermatitis / #eczema) and cancer. I've suffered from those #atopic conditions all my life, and thought of them as the bane of my existence. Then I read one such study sometime around 2015 — and felt like awarding a medal to each individual lymphocyte! (Those are the immune-system cells most directly involved in #atopy.) You see, at age 67, I have zero personal history of cancer, and near zero family history of cancer, even in fairly distant relatives. Before I saw that first article on this subject, it had never occurred to me that those annoying #atopic conditions might be collateral damage from a vigilant and effective patrol against a much worse, and life-threatening, problem.
