NHS England to pilot blood test that detects more than 50 cancers

England's National Health Service (NHS) is scheduled to a launch pilot test of a blood test, developed by US-based company Grail, that can detect 50 types of cancer at early stages. The scheme will be launched in autumn and is aimed at people over 50 years of age with high risk of cancer.

A screen testing for blood test that can detect 50 types of cancer at early stages is to be rolled out by England's National Health Service (NHS). This pilot scheme will be launched in autumn and is aimed at people over 50 years of age with a high risk of cancer. Grail, a US-based company, has developed this test using the method-machine learning algorithm, a kind of artificial intelligence that looks for chemical changes in fragments of genetic code cell-free DNA (cfDNA) that leak from tumours into the bloodstream. The study was conducted on 2,823 people with the disease and 1,254 people without it.
