Key TakeawaysA person's odds for cancer rise soon after a diagnosis of an autoimmune diseaseTreating the illness with anti-inflammatory meds appears to lower cancer riskResearch suggests that inflammation linked to these diseases is the driving force behind the increase in cancer risk.MONDAY, April 6, 2026 (HealthDay News) — Cancer risk is higher for people battling autoimmune diseases, but the danger declines after they start taking anti-inflammatory medications, a new report finds.Italian researchers reporting in the journal Cancers found a 32% increase in the odds for cancer in the first year after a diagnosis for an autoimmune disease such as lupus, rheumatoid arthritis or psoriasis.However, after patients start taking drugs to ease the runaway inflammation that characterizes these illnesses, their cancer risk declines.“The peak risk observed in the early stages suggests that chronic inflammation, rather than treatments, is a key factor in cancer development," said Daniela Marotto, co-senior author of the study. She is head of rheumatology at the Local Health Authority of Gallura, in Italy.Marotto and colleagues tracked the incidence of cancer among more than 356,000 Italians. They found that cancers of the lung and bladder, as well as blood malignancies (such as leukemias and lymphomas) and melanoma were most associated with autoimmune disease. "Our results support the hypothesis that inflammation is a determining factor in cancer risk,” noted study co-author Dr. Antonio Giordano, a professor at the University of Siena in Italy. He is also founder and director of the Sbarro Health Research Organization.Researchers said the finding highlights the need to encourage cancer screening among people with autoimmune diseases, especially in the first year after a diagnosis.More informationFind out more about autoimmune diseases at the Cleveland Clinic.SOURCE: Sbarro Health Research Organization, news release, March 30, 2026 .What This Means For YouCancer risk rises in the year after an autoimmune disease diagnosis, but proper treatment can lower the risk..Sign up for our weekly HealthDay newsletter
