https://medicalxpress.com/cancer-news/ en-us Latest medical news and research in Oncology People with celiac disease and dermatitis herpetiformis have a slightly increased risk of cardiovascular disease, certain types of blood cancer, and premature death. This is shown by a large U.S. registry study led by researchers at Karolinska Institutet. The results are published in the journal The Lancet Regional Health—Americas. https://medicalxpress.com/news/2026-05-celiac-disease-heart-early-death.html Fri, 29 May 2026 14:00:03 EDT news699279721 Healthy lifestyles can reduce the risk of cardiovascular disease and other complications in childhood cancer survivors. These are the findings of two new international studies. https://medicalxpress.com/news/2026-05-lifestyle-childhood-cancer-survivors.html Fri, 29 May 2026 13:40:06 EDT news699279661 The targeted therapy sunvozertinib was more effective than standard platinum-based chemotherapy as a first-line treatment for patients with advanced non-small cell lung cancer (NSCLC) driven by EGFR exon 20 insertion mutations (EGFR exon20ins), according to new research from The University of Texas MD Anderson Cancer Center. https://medicalxpress.com/news/2026-05-drug-outperforms-chemotherapy-patients-hard.html Fri, 29 May 2026 09:00:05 EDT news699262944 In a study published in Science, researchers from The University of Texas MD Anderson Cancer Center have developed a spatial atlas of specialized immune structures, called tertiary lymphoid structures (TLSs), across multiple cancer types. This first-of-its-kind atlas revealed that TLS maturation state, spatial location and composition within tumors may provide clinically meaningful information about cancer prognosis and treatment response. https://medicalxpress.com/news/2026-05-ai-powered-atlas-reveals-insights.html Thu, 28 May 2026 17:40:03 EDT news699207601 Many cancers can be treated by administering DNA-damaging agents, such as platinum-based chemotherapy, because the resulting DNA damage causes the cancer cells to die. A subset of cancers, however, including ovarian cancers, can repair their own DNA. Because such cancers survive despite chemotherapy, ovarian cancer patients whose tumors are DNA repair proficient have historically faced a poor prognosis and commonly recur within six months. https://medicalxpress.com/news/2026-05-scientists-metabolic-chemotherapy-resistance-ovarian.html Thu, 28 May 2026 14:20:03 EDT news699191699 Long regarded as cells involved primarily in allergic responses and antiparasitic defense, eosinophils are now drawing increasing attention in oncology. A review article led by Marie Gilon, an oncology resident physician and Ph.D. candidate at the University of Liège, synthesizes current knowledge on how these white blood cells interact with tumor biology and may inform the clinical management of cancer patients. https://medicalxpress.com/news/2026-05-unexpected-allies-eosinophils-cancer-immunotherapy.html Thu, 28 May 2026 13:40:06 EDT news699191101 Veterans diagnosed with cancer face a higher risk of suicide attempts—especially in the months following diagnosis—and that risk can persist for years, found a large, national study led by Oregon Health & Science University and the Veterans Health Administration. https://medicalxpress.com/news/2026-05-veterans-cancer-years-elevated-suicide.html Thu, 28 May 2026 11:00:06 EDT news699093946 Immunotherapies such as so-called checkpoint inhibitors activate the body's own immune system to fight cancer cells and have revolutionized the treatment of many types of tumor. In breast cancer, however, these therapies are often only of limited effectiveness. An international research team led by the Medical University of Vienna has now identified a previously underestimated mechanism by which breast tumors evade the immune system. https://medicalxpress.com/news/2026-05-breast-tumors-sugar-coating-evade.html Wed, 27 May 2026 15:40:06 EDT news699110102 Oncologists have discovered that lung cancer cells can change their identity to resist treatment. Research published in Molecular Oncology reveals how lung cancer cells can become more aggressive and harder to treat by reactivating a process involved in early lung development. The paper is titled "Developmental programmes drive cellular plasticity, disease progression and therapy resistance in lung adenocarcinoma." https://medicalxpress.com/news/2026-05-lung-cancer-cells-revert-identity.html Wed, 27 May 2026 13:40:01 EDT news699100202 A single blood test could help doctors predict how lung cancer patients will respond to treatment before therapy begins, researchers have found. University of Queensland-led research focused on non-small cell lung cancer (NSCLC), the most common form of the disease, and showed how analyzing proteins in a blood sample could support earlier and better-informed treatment decisions. https://medicalxpress.com/news/2026-05-simple-blood-personalized-lung-cancer.html Wed, 27 May 2026 12:00:03 EDT news699093555 Melanoma is one of the deadliest forms of skin cancer, due in large part to its ability to rapidly develop resistance to treatment. Now, researchers at the University of California San Diego have identified a naturally occurring peptide—a small protein fragment composed of linked amino acids—that may help counter one of cancer's most dangerous survival strategies. https://medicalxpress.com/news/2026-05-naturally-molecule-outsmart-melanoma.html Wed, 27 May 2026 10:40:02 EDT news699093165 For most children diagnosed with medulloblastoma, the most common malignant pediatric brain tumor, survival rates are encouraging. But for a subset, remission is not the end of the story. Roughly 30% of patients will see their cancer return, and once it does, outcomes are often devastating. https://medicalxpress.com/news/2026-05-blocking-cancer-pathways-curb-medulloblastoma.html Tue, 26 May 2026 16:00:06 EDT news699029432 A small clinical trial led by Dana-Farber Cancer Institute researchers has put a Salk Institute idea to the test in patients: that activating the vitamin D receptor can help reshape the protective environment surrounding pancreatic tumors in ways that could make the notoriously difficult-to-treat cancer more vulnerable to therapeutic treatments. https://medicalxpress.com/news/2026-05-vitamin-d-analog-pancreatic-cancer.html Tue, 26 May 2026 15:52:42 EDT news699029406
