NHS: Innovative cancer blood test that detects more than 50 types of cancer in advance

The NHS is experimenting with an innovative new blood test that could detect more than 50 cancers ahead of time.
Galeri blood test, developed by GRAIL, will be piloted on 165,000 people.
previous studies of patients with signs of cancer have found that the test can detect many types of cancer that have traditionally been difficult to diagnose early, such as head and neck cancer, ovarian cancer, pancreatic esophageal cancer, and some blood tumors.
NHS said the test would be extended to everyday use if it showed it could be predicted for asymptomatic people, noting that it would help achieve the NHS's long-term plan to increase the proportion of cancers detected early, which could be key to reducing cancer mortality.
in England, about half of all cancers are currently diagnosed in stage one or two.
, chief executive of NHS England, said: "Early detection, particularly for untreatable diseases such as ovarian and pancreatic cancer, has the potential to save many lives.
GRAIL pilot, which will begin in mid-2021, will involve 165,000 people: 140,000 of them are asymptomatic participants between the ages of 50 and 79, and another 25,000 are those experiencing possible cancer symptoms.
the results of these studies are expected by 2023 and, if confirmed, will expand the scope of the study to attract about 1 million participants between 2024 and 2025."
