Recent comorbidity studies have found associations between rosacea and increased risk for breast and brain cancer.

A recent study in Denmark found rosacea patients had an increased risk of hepatic cancer (liver cancer), nonmelanoma skin cancer and breast cancer, but a decreased risk of lung cancer. The study published in Cancer Epidemiology was conducted by Dr. Alexander Egeberg and a research team from the University of Copenhagen in Denmark.¹ They are responsible for similar recent comorbidity studies connecting rosacea to glioma and gastrointestinal diseases, among other diseases and conditions.
