Study: 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.
