Aspirin's Role In Colon Cancer May Depend On Disease Stage

Key TakeawaysAspirin did not prevent recurrence or death in patients whose colon cancer had spread to the liverThe medicine caused more serious side effects, including bleeding, heart attacks and ulcersAspirin’s benefits may depend on the type and stage of colon cancer, but more research is needed.TUESDAY, Oct. 6, 2026 (HealthDay News) — Aspirin has drawn considerable interest for its potential to lower a person’s risk of developing colon cancer and keep it from coming back.But whether it helps may depend on the stage of the disease."Aspirin is a well-established, inexpensive and widely available drug, and there is considerable interest in whether it can also reduce the risk of cancer recurrence," said lead author Dr. Sheraz Yaqub of the University of Oslo in Norway. "Our findings demonstrate why such treatments must be tested in rigorous randomized trials before being adopted for new patient populations."Scandinavian researchers studied 428 patients who underwent treatment for colon cancer that had spread to the liver.Participants received either daily aspirin or a placebo for up to three years afterwards.The result: Aspirin did not reduce the risk of the cancer returning or death.Serious adverse events were also more common, including bleeding, heart attacks and ulcers.In contrast, another recent trial found aspirin actually reduced recurrence in certain patients with non-metastatic colon cancer."The anticancer effects of aspirin may depend on the biological and clinical context," said co-principal investigator Dr. Kjetil Taskén, also from the University of Oslo.One caveat: The trial only looked at starting aspirin after treatment for colon cancer that had spread to the liver.The authors said patients already taking aspirin for another medical reason should consult their doctor before making changes.The study was recently published in The Lancet Gastroenterology & Hepatology.More informationThe National Cancer Institute has more on colorectal cancer.SOURCE: HealthDay TV, Oct. 6, 2026 .What This Means For YouAspirin does not appear to prevent colon cancer from returning in patients whose cancer has spread to the liver and may cause serious side effects..Sign up for our weekly HealthDay newsletter
