A metal-detecting blood test that can give vital early warning of breast cancer is being developed by Oxford University scientists.
They hope the inexpensive and simple test will spot the disease long before a woman develops a lump – and say it could be used in a national screening programme.
Picking up the cancer at the earliest stages when it is easiest to treat could save thousands of lives, as well as spare patients and their loves ones the pain and distress of prolonged illness.
Researcher Fiona Larner said: 'Prevention is better than cure.
'There is a survival rate of about 80 per cent for breast cancer but the earlier you can detect it, the more chance you have of treating it.
