New testing method means treatments could start sooner, possibly before patient leaves the operating table

A new method for diagnosing brain tumours could cut the time patients wait for treatments by weeks to hours and raise the possibility of novel types of therapy, researchers have said.

According to the Brain Tumour Charity, about 740,000 people around the world are diagnosed with a brain tumour each year, around half of which are non-cancerous. Once a brain tumour is found, a sample is taken during surgery and cells are immediately studied under a microscope by pathologists, who can often identify the type of tumour. However, genetic testing helps to make or confirm the diagnosis.

Resveratrol, which is also found in blueberries and peanuts, has been found to slow tumour growth in mice

Red wine was once heralded as a boon for health that could protect the heart and even extend life expectancy. But while scientists have debunked this claim, they believe that at least one red wine ingredient – a compound called resveratrol – may hold genuine health benefits.

A trial launched this week will assess whether a low dose of the chemical, also found in red grapes, blueberries and peanuts, could help keep bowel cancer at bay. The study, one of the largest to date testing drugs for cancer prevention, will recruit patients who are at risk of the disease.
