CT scan may increase brain tumor risk

New research suggests that consistent aerobic exercise can help keep your brain biologically younger. Adults who exercised regularly for a year showed brains that appeared nearly a year younger than those who didn't change their habits.

Researchers uncovered a powerful weakness in lung cancer by shutting down a protein that helps tumours survive stress.

A sweeping analysis of 85 studies confirms that those who stay active consistently reduce their mortality risk by 30-40%, while even those who become active later in life enjoy a 20-25% reduction. The study has been published in the British Journal of Sports Medicine.

Immunotherapy, or antibody treatment that activates the patient's own immune system against cancer, is increasingly being studied as an alternative to chemotherapy and radiotherapy. This is because it directly targets cancer cells, reducing the negative effects associated with more conventional treatments.

Several studies conducted over the last decade have found that up to a quarter of unresponsive patients with recent brain injuries may have a level of consciousness that is generally hidden from their families and physicians.

Researchers have conducted one of the largest eye studies in the world to reveal new insights into retinal thickness, highlighting its potential in the early detection of diseases like type 2 diabetes, dementia and multiple sclerosis.

The study confirms research completed in 2023, which revealed that anemic patients who received less blood had a higher mortality rate or more frequent heart attacks. Jeffrey L. Carson, provost and Distinguished Professor of medicine at Rutgers Robert Wood Johnson Medical School, led both studies.

"Younger women generally have a higher risk of recurrence than older postmenopausal women, but most studies on anti-hormonal therapy have mainly included postmenopausal women. We therefore wanted to compare the long-term benefit from the treatment in both groups," says Linda Lindstrom, associate professor and research group leader at the Department of Oncology-Pathology, Karolinska Institutet, who led the study.

Researchers at Emory University's Winship Cancer Institute discovered a new form of immune cell known as the stem-like CD4 T cell, which plays an important role in anti-tumor immunity. The pre-clinical findings, published in Nature, indicate the potential for activating these cells to combat tumours more effectively, providing new hope for broader treatment success, particularly in patients with cancer that are unresponsive to conventional immunotherapies.

Glioblastoma is an extremely aggressive brain tumour that is currently incurable. Cancer doctors can increase their patients' life expectancy with surgeries, radiation, chemotherapy, or surgical procedures. Nonetheless, half of patients die within a year of diagnosis.
