One drop of saliva and 'near PERFECT accuracy' 10-MINUTE HOME TEST FOR CANCER.

Byline: Andrew Gregory in Washington DC

SCIENTISTS have developed a cheap and highly-accurate home saliva test which reveals if you have cancer in just 10 minutes.

It is a major breakthrough with the potential to completely revolutionise how the deadly disease is diagnosed.

More than 330,000 people are told they have cancer every year in the UK. But many are already at a late stage, when treatment is less effective.

The PS15 liquid biopsy test could dramatically boost survival rates by providing early diagnosis.

And it could replace blood tests on biopsy samples from patients' tissue. The new test needs just one drop of saliva to check for the disease.

Trials on lung cancer patients in China resulted in "near perfect" accuracy and the lead researcher on the project, Professor David Wong, is confident it will work with a wide range of cancers.

The test, which works by looking for tiny fragments of tumour DNA in the body, is so simple that it could be carried out by a pharmacist, a dentist or even at home with a self-testing kit.

Professor Wong, who is Associate Dean of Research at the University of California Los Angeles, said the saliva test could be available in the UK by the end of the present decade.

Crucial Speaking at the world's biggest science conference in Washington DC, he said: "If there is circulating signature of a tumour in a person's blood or saliva, this test will find it.

"It can be done in a doctor's office while you wait. Early detection is crucial. Any time you gain in finding out that someone has a life-threatening cancer, the sooner the better. It can be implemented by the patients themselves in a home check, or dentist or pharmacy."

Addressing a meeting of the American Association for the Advancement of Science, Prof Wong said: "Down the road it might be possible to test for multiple cancers at the same time. The advantage of our technology is that it is non-invasive. If you have a credible early screening risk assessment technology that's the key - early detection."

He told conference delegates from Britain: "I would love to do it in the UK by the end of this decade. I would hope sooner than that."

His team came up with the test after discovering that saliva contains many of the same disease-revealing molecules that are in blood.

In his research paper, Prof Wong wrote that current cancer tests, like biopsies, were "limited in scope". But he added: "There appears to be treasure in saliva."
