A natural citrus oil from oranges, lemons, and limes is proving highly effective in relieving dry mouth, and when combined with a new lipid formulation, new research suggests it may be effective without significant side effects.

Developed by the University of South Australia in collaboration with the Medical School at Stanford University, this world first formulation uniquely combines limonene (a citrus essential oil) with a lipid-based drug delivery system to treat dry mouth (xerostomia), a common side effect of radiotherapy.

A simple urine test could accurately show the recurrence of kidney cancer at an early stage, potentially sparing patients invasive scans and enabling faster access to treatment, new research has shown.

Biopsies guided by high resolution ultrasound are as effective as those using MRI in diagnosing prostate cancer, an international clinical trial has shown.

Two doses of a simple tuberculosis vaccination after surgery helps the immune system fight cancer cells and could greatly improve patient outcomes for the most common type of bladder cancer, according to a pilot study of 40 patients.

New research to be presented at this year’s European Congress on Obesity (ECO 2025, Malaga, Spain, 11-14 May) shows that a new diagnosis of type 2 diabetes is linked to a subsequent increase in the risk of developing some, but not all, obesity related cancers. The study is by Owen Tipping, University of Manchester, UK, and Professor Andrew Renehan, National Institute for Health Research (NIHR) Manchester Biomedical Research Centre, Manchester, UK, and colleagues.

Body size and excess weight, conventionally assessed using body mass index (BMI), are well-established risk factors for many types of cancer. However, new research to be presented at this year’s European Congress on Obesity (ECO 2025, Malaga, Spain, 11-14 May) and published in The Journal of the National Cancer Institute shows that waist circumference (WC) is a stronger risk marker than BMI for developing obesity-related cancers in men, but not women. The study was conducted by Dr. Ming Sun, Dr. Josef Fritz and Dr. Tanja Stocks, Lund University, Malmö, Sweden, and colleagues.
