New Cancer Test Can Detect Any Cancer in Minutes

Universal Cancer Test One Test to Diagnose Them All

Universal Cancer Test One Test to Diagnose Them All

In an affordable and simple test uses a fluid that changes color to identify the presence of malignant cells in any place of the body and gives results in less than 10 minutes.

These distinct patterns of molecules control which genes are turned on and off at any given time and "decorate the DNA".

The test they've developed involves extracting purified DNA from blood or tissue and then adding it to a gold particle solution to see how well it binds.

DNA inside normal cells has methyl groups dotted all over; inside cancer cells it is largely bare with methyl groups found in small clusters in specific locations.

According to sources familiar with the matter, the test was developed after the Australian researchers of the University of Queensland discovered that the cancer cells form a unique genetic pattern when placed under water. These groups act like beacons that turn our DNA genes on and off.

This unique signature, which the authors are calling the cancer methylscape, was found in every type of breast cancer that was tested, as well as in prostate cancer, lymph, ma and colorectal cancer.

It has shown to be up to 90% accurate in tests of 200 human cancer samples and normal DNA, they said, though it has not been tested in a clinical trial. The Guardian details more info about how this test is conducted, so make sure to give the article a look. If 3D nanostructures of cancer DNA exist, the gold nanoparticles will instantly change color.

"This is a huge discovery that no-one has grasped before", said Laura Carrascosa, a researcher at the University of Queensland.

"This test could be done in combination with other simple tests, and become a powerful diagnostic tool that could not just say that you have cancer, but also the type and stage", said Carrascosa.

The test has 90 per cent sensitivity, which means that it would be able to trace cancerous elements in 90 out of 100 cases.

The researchers acknowledged that their test needs further study, "but it looks really interesting as an incredibly simple "universal marker" of cancer", Trau said in the statement.

"We believe that this simple approach would potentially be a better alternative to the current techniques for cancer detection". "When cancer happens, the tree loses most of its decoration. We haven't tested that yet, but it is a potential".

It's also attractive "as a very accessible and low-priced technology that does not require complicated lab-based equipment like DNA sequencing", he said.

Using a festive season analogy, Dr Carrascosa said it was similar to finding different decorations on Christmas trees.
