A blood test to discover 50 tumors, promising test in Gb

Researchers at the British National Health Service (NHS) have shown promising results in the trial conducted in recent months on thousands of volunteers in the United Kingdom of a type of blood test - the Galleri Test - developed in the US by a Californian laboratory to help detect up to 50 different forms of cancer through early detection. This was reported by the BBC, taking up the results of a paper prepared ahead of a medical conference organized in Chicago by the American Society of Clinical Oncology.
The British trial of the Galleri test is the first in the world on a sample of this magnitude. Conducted on 5000 patients with suspicious symptoms who went to hospitals and public health facilities in England and Wales, it produced correct positive diagnoses in two-thirds of cases, as later confirmed by traditional methods such as biopsies or ultrasounds.
It also helps doctors, in 85% of them, to identify exactly the point of onset of tumors.
The University of Oxford, which participated in the screening, also stressed that it is a path of experimentation not yet concluded, of "a work in progress" to be completed with further studies and verifications. But he expressed optimism that we can be faced with one more effective tool for the timely diagnosis of oncological diseases.
75% of people tested positive did indeed have cancer, according to published numbers. While only 2.5% of negative outcomes turned out to be ultimately fallacious and denied by other diagnostic means by the presence of a tumor.
