Detecting lung cancer early is critical to a patient's survival, but how early is early enough? Florida International University math professor and researcher Deborah Goldwasser is uncovering new findings that could identify the mathematical tipping point between curable and terminal cancer. Her work could change how doctors determine the best timing for lung cancer screening by correcting statistical biases that may be overestimating the window for curing aggressive cancers. https://medicalxpress.com/news/2026-09-mathematical-curable-window-fast-lung.html Thu, 10 Sep 2026 09:40:04 EDT news708250321 It's one of the cruelest ironies in health and medicine. Pediatric sarcomas are among the rarest yet most aggressive forms of childhood cancer and some of the hardest to cure. Whereas many adult cancers are now treatable with new therapeutic strategies, such as immunotherapies, pediatric sarcomas have not seen nearly as many advances. Survival rates have remained largely unchanged for decades. https://medicalxpress.com/news/2026-09-child-cancer-groups-concerted-action.html Thu, 10 Sep 2026 09:20:09 EDT news708250022 The National Comprehensive Cancer Network (NCCN)—an alliance of leading cancer centers—has published updated data on the current impact of generic cancer medication shortages in the United States. The data come from survey responses from pharmacy directors and other clinical and administrative leaders at NCCN Member Institutions from late August. According to the results, 100% of responding cancer centers are experiencing a shortage of at least one anticancer agent, with more than 20% of centers currently experiencing shortages of five or more different medications. https://medicalxpress.com/news/2026-09-survey-highlights-persistent-cancer-medication.html Thu, 10 Sep 2026 09:00:03 EDT news708189061 Inside the hazard simulation lab at Iowa State University, Guowen Song watches a column of engineered smoke curl upward from a controlled burn. https://medicalxpress.com/news/2026-09-statewide-effort-cancer-firefighters.html Thu, 10 Sep 2026 08:00:08 EDT news708239281 Patients with locally advanced head and neck squamous cell carcinoma (HNSCC) whose tumors responded to neoadjuvant immunochemotherapy (ICT) and who underwent less extensive surgery had high disease-free survival and organ preservation rates, according to a study published in Clinical Cancer Research, authored by Kunyu Yang, MD, director of Union Hospital Cancer Center at Tongji Medical College and Huazhong University of Science and Technology in China, and others. https://medicalxpress.com/news/2026-09-tumor-response-immunochemotherapy-neck-cancer.html Thu, 10 Sep 2026 03:10:01 EDT news708189301 Senior urban development decision-makers have revealed there is currently little incentive to consider public health impacts when shaping towns and cities, according to a new study published in Evidence & Policy that highlights the potential of an innovative economic valuation tool to address the problem. https://medicalxpress.com/news/2026-09-economic-tool-cities-prioritize-health.html Wed, 09 Sep 2026 20:00:01 EDT news708165950 A multi-institutional research team led by Georgia State University Regents' Professor Emerita of Biochemistry and Biophysical Chemistry Jenny J. Yang has developed a new class of protein-based MRI contrast agents that detect invasive lung cancer and metastatic disease at earlier stages than conventional imaging approaches. Results of this research, recently published in the journal Science Advances, report a precision MRI method that can identify tumors and metastases as small as 1 millimeter. https://medicalxpress.com/news/2026-09-protein-based-mri-agent-lung.html Wed, 09 Sep 2026 19:20:01 EDT news708193382 Most patients with localized appendix cancer may be able to safely avoid chemotherapy after surgery, according to a new study from researchers at The University of Texas MD Anderson Cancer Center. https://medicalxpress.com/news/2026-09-patients-appendix-cancer-chemotherapy-surgery.html Wed, 09 Sep 2026 19:00:07 EDT news708193261 Cancer cell metabolism may play a key role in tumors' ability to evade the immune system. In a study published in the Journal for ImmunoTherapy of Cancer, researchers from GIGA demonstrate that methylglyoxal, a byproduct of tumor metabolism, contributes to the creation of an environment that favors the progression of triple-negative breast cancer and resistance to immunotherapy. https://medicalxpress.com/news/2026-09-triple-negative-breast-cancer-tumor.html Wed, 09 Sep 2026 15:40:09 EDT news708177662 An international research team led by Dr. Lucia Torres Fernández from the working groups of Professor Dr. Julie George and Professor Dr. Roman Thomas at the University of Cologne has identified a critical dependency in small cell lung cancer (SCLC) that can be exploited therapeutically. https://medicalxpress.com/news/2026-09-cancer-shield-blocking-pathway-small.html Wed, 09 Sep 2026 15:20:06 EDT news708183181 Seven years ago, Johns Hopkins researchers and their collaborators announced they had found the X cell, a novel immune cell that plays a key role in the development of type 1 diabetes. https://medicalxpress.com/news/2026-09-preclinical-antibody-approach-aims-diabetes.html Wed, 09 Sep 2026 14:40:05 EDT news708177571 In 2024, malignant tumors caused more than 21,300 deaths in Austria, 4.7% more than in 2014. Faced with a similarly pressing global challenge, scientists are striving to better understand what drives cancer cells to grow, spread and invade healthy tissue. https://medicalxpress.com/news/2026-09-microscopic-obstacle-hints-disorder-prime.html Wed, 09 Sep 2026 14:00:17 EDT news708174781 Researchers at The University of Texas MD Anderson Cancer Center have uncovered a possible reason why metastatic medullary thyroid cancer causes abnormal bone growth, pointing to a new opportunity to detect and monitor bone metastases in patients. https://medicalxpress.com/news/2026-09-blood-bone-metastasis-medullary-thyroid.html Wed, 09 Sep 2026 13:20:04 EDT news708177421 There is no "one-size-fits-all" treatment for patients living with cancer. Cancer occurs when normal cells in the body genetically mutate and transform into abnormal cells that divide uncontrollably. https://medicalxpress.com/news/2026-09-miniature-fluidic-devices-enable-personalized.html Wed, 09 Sep 2026 13:00:04 EDT news708165061 Mayo Clinic researchers have identified a potential new approach to treating glioblastoma that could help the immune system fight the aggressive brain cancer while improving the effectiveness of existing chemotherapy. https://medicalxpress.com/news/2026-09-inhibitor-tumor-immune-cells-glioblastoma.html Wed, 09 Sep 2026 12:40:06 EDT news708172381 Researchers at the University of Rochester thought that shutting down a protein linked to inflammation might help slow aging. Instead, they found the opposite: Without the protein, mice became frailer, experienced more inflammation and had shorter life spans. https://medicalxpress.com/news/2026-09-cgas-protein-aging-worse-unleashing.html Wed, 09 Sep 2026 11:40:10 EDT news708170807 As more individuals with cerebral palsy live well into adulthood, medical professionals are taking a closer look at the unique long-term health care needs of this patient population. While adults with cerebral palsy require the same routine health maintenance as anyone else, a large national study conducted at Yale showed that women living with cerebral palsy received significantly less preventive gynecologic care than women without the condition. https://medicalxpress.com/news/2026-09-women-cerebral-palsy-vital-gynecologic.html Wed, 09 Sep 2026 11:20:04 EDT news708163921 A new scientific statement released today by the Endocrine Society highlights the benefits of obesity treatment beyond weight loss, including improved overall health and reduced risk of conditions such as heart disease, sleep apnea and liver disease. https://medicalxpress.com/news/2026-09-health-obesity-treatment-weight-loss.html Wed, 09 Sep 2026 11:00:24 EDT news708003361 Prostate cancer is the second most common form of cancer among men globally. Yet, we still know relatively little about why the disease develops or why some men live with it for years while it progresses aggressively in others. https://medicalxpress.com/news/2026-09-dna-signatures-reveal-prostate-cancers.html Wed, 09 Sep 2026 11:00:20 EDT news708169081 Mutations are changes in the molecular "letters" that make up DNA, the genetic blueprint for cells. Mutations build up with age in every cell when DNA is damaged or when cells make mistakes in fixing or copying it. Most mutations are harmless, but when they disrupt genes, they can cause cancer and other diseases. https://medicalxpress.com/news/2026-09-calorie-restriction-reveals-potential-age.html Wed, 09 Sep 2026 11:00:04 EDT news708168842 Facing major surgery is stressful, but for older adults, unaddressed anxiety and depression can impede physical recovery. A clinical trial led by researchers at Washington University School of Medicine in St. Louis found that starting an intervention before surgery—one that combines mental health coaching with optimization of medications that may increase risks for older adults—reduces postsurgery anxiety and depression. https://medicalxpress.com/news/2026-09-clinical-trial-adding-mental-health.html Wed, 09 Sep 2026 11:00:01 EDT news708003481 Lung cancer is the leading cause of cancer death in the United States, claiming more than 125,000 lives each year. There is a quick, painless screening test that can detect lung cancer before symptoms appear, when treatment is more effective. Yet more than 80% of those eligible for a low-dose CT scan (LDCT) never get screened. https://medicalxpress.com/news/2026-09-needle-lung-cancer-screenings-medical.html Wed, 09 Sep 2026 10:20:09 EDT news708163442 Roughly half the world's population is infected with the stomach bacterium Helicobacter pylori, which is responsible for about 90% of gastric cancers. However, until now, it has been unclear why some H. pylori infections lead to a rare form of lymphoma in the stomach while others don't. https://medicalxpress.com/news/2026-09-immune-protein-loss-rare-stomach.html Wed, 09 Sep 2026 10:00:14 EDT news708158882 New research presented at the Annual Meeting of the European Association for the Study of Diabetes (EASD) in Milan, Italy, shows that people who have had COVID-19 have a lower, rather than higher, risk of subsequently developing type 1 diabetes (T1D). https://medicalxpress.com/news/2026-09-analysis-links-covid-infection-unvaccinated.html Wed, 09 Sep 2026 10:00:11 EDT news708165481 Colonoscopies are one of the most effective ways to prevent colorectal cancer, which is surging among young adults in the U.S. Yet, the quality of each procedure can vary substantially from one physician to another. As a result, medical societies recommend routinely reviewing every colonoscopist—something that's challenging and time-consuming for practices to implement. https://medicalxpress.com/news/2026-09-colonoscopies-ai-scale.html Wed, 09 Sep 2026 09:20:13 EDT news708162181 New research indicates that people with invasive cancer face an elevated risk of experiencing a stroke, especially in the first few months after diagnosis and if they have certain types of cancer. The findings are published online by Wiley in Cancer. https://medicalxpress.com/news/2026-09-higher-months-cancer-diagnosis.html Wed, 09 Sep 2026 03:00:01 EDT news708011431 One of the above images is real; the other is AI-generated. Can you tell which is which? The images depict intestinal polyps, often benign growths on the inside of the colon or rectum. Polyps are usually removed because some can develop into bowel cancer over time. https://medicalxpress.com/news/2026-09-ai-doctors-intestinal-disease.html Tue, 08 Sep 2026 19:20:08 EDT news708101161 Exposure to the stomach microbe Helicobacter pylori may be associated with more than 1 in 5 cases of colorectal cancer worldwide, suggests an exploratory risk-attribution study published in the journal eGastroenterology. https://medicalxpress.com/news/2026-09-stomach-microbe-exposure-linked-bowel.html Tue, 08 Sep 2026 18:30:03 EDT news707993237 Severe eosinophilic asthma can now be treated with biologic therapies that reduce attacks and, in some cases, allow corticosteroid dose reductions. However, not all patients respond to these treatments, and it remains difficult to predict in advance who will benefit from them. A study conducted by scientists at the University of Liège and Liège University Hospital proposes using a "simple" breath sample to guide treatment selection even before it begins. The findings are published in the American Journal of Respiratory and Critical Care Medicine. https://medicalxpress.com/news/2026-09-response-biologics-severe-asthma-analysis.html Tue, 08 Sep 2026 17:40:05 EDT news708099722 T-cell receptor, or TCR, therapy is a cancer treatment that genetically reprograms immune cells, called T cells, to hunt down cancer with precision. It's similar to another treatment, CAR T-cell therapy, but with one key difference: CAR T-cell therapy can only spot proteins that naturally appear outside a cancer cell. TCR therapy, however, can also catch small protein fragments from inside the cell that are carried to the surface and displayed like little name tags. https://medicalxpress.com/news/2026-09-scientists-ready-cancer-cells-solid.html Tue, 08 Sep 2026 17:00:01 EDT news708096997
