Data suggest that the incidence rates of overall cancer and cancer subtypes, including lymphoma and nonmelanoma skin cancer, are similar in patients with psoriatic arthritis and those with rheumatoid arthritis, even after adjustment for numerous potential confounders, including age, race, sex, disease activity, disease duration, year of enrollment, and medication use.

Data are conflicting regarding an increased risk for melanoma and nonmelanoma skin cancers in patients with psoriatic arthritis, but guidelines state that most studies show the risk is equivalent to that of the general population.

Studies have not shown an increased risk for solid malignant tumors in patients with psoriatic arthritis.
