RESEARCHERS in the UK have ‘hidden’ cancer-killing viruses in white blood cells so they can ‘sneak’ them into a tumour. When inside, tens of thousands of viruses were released to kill the cancerous cells.
At the end of the 40-day trial, all the mice that received the treatment were still alive and had no signs of cancer. However, cancer spread in the mice that received other treatments, and some of them died.
All the mice had advanced prostate tumours, and had already been treated with chemotherapy and radiotherapy.
Researchers hope to begin human trials in 2013 but warn that many trials that involve treating mice, fail to have any effect on humans.
Dr Emma Smith, from Cancer Research UK, said: “Harnessing the body’s own immune system to deliver a deadly virus to tumours is an exciting approach that many scientists are pursuing.”
The number one thing you can do to reduce the risk of cancer – after giving up smoking – is to lose weight. Being overweight is linked with around 20,000 deaths from cancer each year. Ideally, your body mass index (BMI) should be between 20 and 25.
To achieve this, eat a healthy diet rich in fruit and vegetables, plus oily fish, nuts, seeds and wholegrains.
