Description
Kyeong Min Han and colleagues ask whether psoriasis raises colorectal cancer risk, in a 2026 nationwide Korean cohort study. Insurance data from 2002 to 2019 supplied more than sixteen thousand patients with psoriasis and four matched controls for each. Weighting balanced other health and social factors between the groups.
Colorectal cancer appeared at comparable rates in both groups, and the adjusted estimate showed no increased risk from psoriasis. Subgroup checks by age, sex, income, region, and comorbidity burden gave the same null pattern. The authors conclude psoriasis alone does not justify extra colorectal screening beyond standard recommendations, even where cancer burden is high.
