Neurosurgeons across the globe are faced with the question as to striking the correct balance between a "radical" tumor resection and avoiding further neurological damage. https://medicalxpress.com/news/2026-01-standards-brain-tumor-surgery.html Mon, 19 Jan 2026 21:00:04 EST news688049987 A world-first study led by Austin Health's clinician-researchers has demonstrated the feasibility and safety of using stabilized hyaluronic acid (sHA) gel as a rectal spacer during radiation treatment for gynecological cancers. https://medicalxpress.com/news/2026-01-hyaluronic-acid-key-gynecological-cancer.html Sat, 17 Jan 2026 13:10:05 EST news687694159 To help meet the potentially complex needs of patients after prostate cancer treatment and offer the precision and care necessary in the follow-up journey, Mayo Clinic's Department of Radiation Oncology developed the PSA Control Tower. This is an intelligent monitoring tool designed to support clinicians in keeping a close, ongoing watch over patients after treatment. https://medicalxpress.com/news/2026-01-prostate-cancer-recurrence-power-ai.html Thu, 15 Jan 2026 09:50:07 EST news687692091 Many people are surprised to learn that clinical trials aren't just for people who have run out of standard treatment options, but are an important part of cancer care at every stage and most aspects of diagnosis and treatment. They help physicians study new and better ways to diagnose, treat and improve the quality of life for people. They also give patients access to promising treatments that they might not otherwise receive. https://medicalxpress.com/news/2026-01-cancer-clinical-trial.html Wed, 14 Jan 2026 18:00:01 EST news687606689 According to new research, radiation therapy administered before surgery rarely produces favorable responses in patients with retroperitoneal sarcoma (RPS), a rare and aggressive cancer that forms in the abdomen. The study reinforces findings from a major international clinical trial and suggests that due to ineffectiveness, radiation should not be used to shrink tumors before surgery. https://medicalxpress.com/news/2026-01-therapy-surgery-rarely-retroperitoneal-sarcoma.html Wed, 14 Jan 2026 14:40:39 EST news687624001 Doctors encounter death and dying significantly more than most people.

Though often remarkably effective, removing only the cancerous tissue is a challenge for doctors and surgeons. With no intraoperative method to analyze excised tissues, a surgeon typically must rely on preoperative visualizations—ultrasounds, MRIs, and the like—to accurately locate cancerous tissue and then postoperative examinations of the excised tissue to determine whether the cancer has been entirely removed. https://medicalxpress.com/news/2026-01-intraoperative-tumor-histology-enable-effective.html Mon, 12 Jan 2026 14:27:28 EST news687450422 In Australia, we are exposed to some of the harshest and most dangerous levels of ultraviolet radiation (UV) in the world, so many of us know how important high SPF sunscreen is. https://medicalxpress.com/news/2026-01-sunscreen-wars.html Fri, 09 Jan 2026 17:30:02 EST news687172909 Mayo Clinic researchers have developed and evaluated MedEduChat, an electronic health record (EHR) that works with a large language model to provide accurate, patient-specific prostate cancer education. https://medicalxpress.com/news/2026-01-electronic-health-ai-agent-advances.html Wed, 07 Jan 2026 16:30:01 EST news687025313 Researchers at the UNC School of Medicine and the UNC Eshelman School of Pharmacy have made a breakthrough that could modernize treatment for glioblastoma.

The damage can lead to side effects that may be severe for some patients. In a new nationwide study published in The Lancet that included Mayo Clinic, investigators found that patients with oropharyngeal cancer can live longer with fewer side effects if treated with proton beam radiation therapy. https://medicalxpress.com/news/2025-12-proton-therapy-boosts-throat-cancer.html Mon, 15 Dec 2025 14:30:01 EST news685031189 A study published in The Lancet showed a significant survival benefit for patients with oropharyngeal cancers who were treated with proton therapy (IMPT) compared to those treated with traditional radiation therapy (IMRT). https://medicalxpress.com/news/2025-12-proton-therapy-survival-benefit-phase.html Thu, 11 Dec 2025 18:30:09 EST news684676921 Preoperative radiation improved T-cell infiltration (TCI) in patients with hormone receptor (HR)-positive, HER2-negative breast cancer when administered in combination with pembrolizumab (Keytruda) and chemotherapy and led to improved treatment responses prior to surgery, according to the results of a Phase II P-RAD clinical trial presented at the San Antonio Breast Cancer Symposium (SABCS), held December 9–12, 2025. https://medicalxpress.com/news/2025-12-preoperative-antitumor-immune-response-common.html Thu, 11 Dec 2025 08:20:01 EST news684581222 Researchers at The University of Texas MD Anderson Cancer Center have characterized the complex microenvironment in angioimmunoblastic T cell lymphoma (AITL), a type of nodal T cell lymphoma, and identified overexpression of the CD40 protein as a potential biomarker associated with improved overall survival (OS). https://medicalxpress.com/news/2025-12-cd40-potential-biomarker-nodal-cell.html Tue, 09 Dec 2025 05:51:29 EST news684481862 It's pretty normal to wear the same pair of jeans, a jumper or even a t-shirt more than once. But what about your socks? https://medicalxpress.com/news/2025-12-pair-socks.html Mon, 08 Dec 2025 20:30:06 EST news684421161 While targeted radiation can be an effective treatment for brain tumors, subsequent potential necrosis of the treated areas can be hard to distinguish from the tumors on a standard MRI. A new study published today led by a York University professor in the Lassonde School of Engineering found that a novel AI-based method is better able to distinguish between the two types of lesions on advanced MRI than the human eye alone, a discovery that could help clinicians more accurately identify and treat the issues. https://medicalxpress.com/news/2025-12-ai-technique-distinguish-brain-tumors.html Mon, 08 Dec 2025 15:45:53 EST news684431102
