Life-saving spit test could identify prostate cancer risk - for just £7

A test that uses spit samples to predict which men are at greatest risk of prostate cancer could save hundreds of lives every year, say health experts.The genetic test,  which should cost between £7 and £10, allows doctors to identify the 1 per cent of men at highest risk of developing the disease, which affects nearly 50,000 UK men every year.

Doctors hope that in two years, GPs will be able to test all men on their 40th birthday.

These patients identified as being 'at risk' would then be given advice, as well as MRI scans and biopsies if necessary, meaning that any potential tumours could be spotted early and treated accordingly.
