A group of researchers claim that they have created a “breakthrough” blood sample that could identify the presence of cancer. While such a test sounds promising, it is not necessarily foolish, warned experts.
In analyzing healthy cells and cancer cells, researchers at the University of Queensland in Australia found cancer DNA fragments that stuck on solid surfaces like metals in a wide variety of ways. Using that information, they developed a “simple” test where blood would be mixed with a solution containing gold nanoparticles, according to an article published in Nature Communications, a peer-reviewed, open-access scientific journal. If cancer of any kind occurs in the blood, the gold nanoparticles change color.
“Discovering that cancer DNA molecules formed completely different 3D nanostructures from normal circulating DNA was a breakthrough that has enabled a completely new method of detecting cancer free-invasive in any tissue including blood,” said Matt Trau, a professor at the University of Queensland and one of the co-authors of the study, in a statement.

The researchers argued that their tests could pave the way for a cheaper and faster cancer diagnosis process. The testing process only takes 1
0 minutes and can be adjusted to occur within a cheap and portable diagnostic device, they said. “We really do not know if it is the sacred degree of all cancer diagnosis, but it looks very interesting as an incredibly simple universal cancer marker and as an accessible and cheap technique that does not require complicated laboratory-based equipment such as DNA sequencing,” said Trau.
Observers were most doubtful when they celebrated the news. It’s really just the latest example of a “single” cancer blood sample. In June, a separate group of US scientists announced that they had created a blood sample that could identify as many as 10 types of cancer. And in January, researchers from Johns Hopkins School of Medicine announced the wording of a $ 500 blood sample called CancerSEEK, which could identify eight types of cancer before the symptoms developed.
“I have often said that whenever you hear of a simple cancer test,” run for the hills because there’s no such thing “, wrote Gary Schwitzer, founder and publisher of HealthNewsReview.org, in an article warning of caution about the latest blood test. “This researcher can refer to technology, but the application of the technology-language from bed to bed-brings it many levels of complexity.”
In particular, Australian researchers noted that their test successfully identified 90% of cancer attack, but as Schwitzer noted “the statement of an incredibly simple universal marker begins to hear a little hollow” for those whose cancer was not identified by the test.
In addition, the test is claimed to identify if anyone has cancer at first, it can not yet decide the origin or severity of the disease. For this, patients would have to go through additional tests, which takes time and can cause anxiety t.
Others expressed concern about whether the test could give false positive results that could force people to go through unnecessary testing and stress.
