Fewer cases of melanoma and cancers in extracutaneous sites among people with atopy
Fewer cases of melanoma were observed in people with a history of atopic diseases, such as allergic asthma or rhinitis, than in nonatopic people. The risk of melanoma in people with atopy was up to 50% lower than in the control group. In addition, people with atopy had a considerably lower overall risk of skin cancer, according to estimates by experienced dermatologists. The prevalence of cancers in extracutaneous sites was also lower in atopic people. The study, conducted in collaboration between the University of Eastern Finland and Kuopio University Hospital, included nearly 500 people
