The UK government is developing a groundbreaking blood test that can detect 12 common and lethal cancers before symptoms arise, with Health Secretary Wes Streeting highlighting its potential to revolutionize cancer treatment. This 'universal' blood screening, utilizing technology similar to PCR tests from the pandemic, is being spearheaded by scientists at the University of Southampton and is projected to be ready for NHS use in five to seven years. The test, costing £120, could significantly reduce the time patients wait for diagnoses and potentially save thousands of lives annually. Government funding of £2.5 million will enhance the test's speed and accuracy, with an emphasis on its application across diverse populations. Streeting emphasized that catching cancer early is crucial not only for saving lives but also for bolstering the UK’s economy. The initiative is part of a broader investment of £148 million in life sciences, expected to stimulate growth and create jobs.
