'Liquid Biopsy' Screens Blood for Cancer Before Symptoms Detectable

New blood test detects ten cancer types years earlier, say scientists working on the research.

Together, the three tests were able to detect 10 dfferent types of cancer, including colorectal, esophageal, lung, pancreatic, and ovarian.

The results for triple-negative breast cancer were 58 per cent, and the test also detects lung, gullet and head and neck cancers with more than 50 per cent accuracy. Scientists at Grail, a U.S. company funded by Mr Gates and Mr Bezos, have set their sights on identifying a range of cancers from a...

Dr. Klein says the procedure still needs more testing but suggested that this "holy grail" could eventually become a standard screening method for people as they age. According to The Telegraph, the UK's National Health Service (NHS) could start using the blood test within the next five years, but some state that figure is overly ambitious. One of the issues is the blood-brain barrier that protects the brain.

USA military killed almost 500 civilians in 2017, Pentagon says
The Defence Department "has no credible reports of civilian casualties resulting from US strikes in Somalia in 2017", the report said .

The test is called liquid biopsy and it's being hailed as the "holy grail of cancer research".

The findings were presented at the annual conference of the American Society of Clinical Oncology in Chicago.

The test's high sensitivity to pancreatic cancer is especially promising.

It was 77 per cent accurate in diagnosing lymphoma, 73 per cent accurate for myeloma, and 80 per cent accurate for liver and gallbladder cancers.

It was less able to pick up stomach, uterine and early-stage low-grade prostate cancer. The symptoms can often be quite generic, like tiredness and weight loss, so many people don't find out they have the disease until it has really taken hold. The test is a "liquid biopsy", which is a type of screening that is generally seen as having advantages over traditional biopsies, which require an actual tissue sample from parts of someone's body.

Nicholas Turner from London's Institute of Cancer Research said, via The Guardian.

He said: ‘Far too many cancers are picked up too late, when it is no longer possible to operate and the chances of survival are slim. "The goal is to develop a blood test, such as this one, that can accurately identify cancers in their earliest stages".

Simon Stevens, chief executive of NHS England, said such advances in medicine could "dramatically transform" care.

He warned that the ECP may have an even bigger role to play in the run-up to the election, and had not been properly reformed. He has served as a judge in Peshawar High Court, Chief Justice of Pakistan and Chief Election Commissioner too.

"In particular, new techniques for precision early diagnosis would unlock enormous survival gains, as well as dramatic productivity benefits in the practice of medicine".
