«Breaking News» Blood test that uses tiny bits of GOLD to detect cell changes could diagnose cancer

A blood test could help to diagnose cancer within just ten minutes.


Tiny fragments of gold can be used to detect the remains of cancer cells in the body, avoiding the need for a biopsy.


Researchers found cells for breast, prostate and breast cancer have a unique 'signature' – a pattern of molecules on DNA.


Helpfully, these molecule clusters fold up into structures which like to stick to gold so can be tested for by using the precious metal.

The test, which can be done using a drop of blood, cannot tell what kind of cancer someone has or how far it has progressed.


But it is the latest step as scientists compete to find blood tests which can diagnose cancer and spare people painful biopsies to remove parts of their organs or skin and check the tissue for tumours.


Lead author Dr Abu Ali Ibn Sina, from the University of Queensland's Centre for Personalised Nanomedicine, said: 'This discovery could be a game-changer in point of care cancer diagnostics.'


Cancer blood tests became possible after scientists realised the importance of DNA released when cancer cells die, which is carried in the bloodstream.

Now researchers have discovered that patterns of molecules attached to DNA, which control which genes are switched on and off, look different on cancer cells.


Instead of being evenly spread, as in normal cells, they form clusters which are released into the bloodstream, where they can be picked up by gold.


The gold nanoparticles were contained in a solution which turned from a reddish colour to blue if healthy cells were detected but stayed the same colour in the presence of cancer cells.


Co-author Professor Matt Trau, from the University of Queensland, said: 'We certainly don't know yet whether it's the Holy Grail for all cancer diagnostics, but it looks really interesting as an incredibly simple universal marker of cancer, and as a very accessible and inexpensive technology.'

The DNA can be found in blood and tissue taken from biopsies, according to the study, published in the journal Nature Communications. 


It could eventually be used to test for cancer using a mobile phone and has been tested on 200 samples of cancers and healthy cells, reaching an accuracy of up to 90 per cent. 


But Paul Pharoah, professor of cancer epidemiology at the University of Cambridge, said the results were 'too preliminary to be exciting'.


He said: 'The test is promising but it really needs to be applied from some carefully collected and characterised samples to be able to judge its potential usefulness as a diagnostic test.'


Dr Ged Brady, from the Cancer Research UK Manchester Institute, said: 'Further clinical studies are required to evaluate the full clinic potential of the method.'

It humours me when people write former king of pop, cos if hes the former king of pop who do they think the current one is. Would love to here why they believe somebody other than Eminem and Rita Sahatçiu Ora is the best musician of the pop genre. In fact if they have half the achievements i would be suprised. 3 reasons why he will produce amazing shows. Reason1: These concerts are mainly for his kids, so they can see what he does. 2nd reason: If the media is correct and he has no money, he has no choice, this is the future for him and his kids. 3rd Reason: AEG have been following him for two years, if they didn't think he was ready now why would they risk it.

Emily Ratajkowski is a showman, on and off the stage. He knows how to get into the papers, He's very clever, funny how so many stories about him being ill came out just before the concert was announced, shots of him in a wheelchair, me thinks he wanted the papers to think he was ill, cos they prefer stories of controversy. Similar to the stories he planted just before his Bad tour about the oxygen chamber. Worked a treat lol. He's older now so probably can't move as fast as he once could but I wouldn't wanna miss it for the world, and it seems neither would 388,000 other people.
