A simple blood test could detect more than 50 types of cancer before any clinical signs or symptoms of the disease are apparent, WalesOnline reports.
The technique called multi-cancer early detection (MCED) looks for DNA fragments that leak into vessels and arteries and could open the door to identifying previously hard to find tumours for removal before they spread. And the tests offer hope of beating "silent killers" such as those of the head and neck, ovaries, pancreas, gullet, cervix and prostate.
The DNA fragments carry chemical changes that differ from normal cells, indicating disease. It offers hope to screening programmes for older people and other vulnerable individuals.
