Researchers develop quick, easy cancer detection test

Researchers develop quick, easy cancer detection test

A report in The Guardian explained the affordable procedure as involving a cheap and simple test using a colour-changing fluid to show the presence of these cells in the body within ten minutes, making it a radical new approach to detect cancer using simple procedures.

Although the test is still in development, it uses a radically new approach to the detection of cancer, which can make screening for cancer a simple procedure.

In its current form, the test would be less applicable as a screening test, given that it can not detect types of cancer, Ohm told Live Science.

Co-researcher Abu Sina said the findings represented a "significant discovery" that could be a "game changer" for cancer detection.

In the DNA of healthy cells, small molecules called methyl groups are used as a form of "volume control", turning genes on and off so that they can perform the functions required for the specific kind... In cancer cells, this patterning is hijacked so that only genes that help the cancer grow are switched on. Indeed, this test is so convenient and affordable that in the not-too-distant future we could all be carrying around our own personal cancer detector - on our cell phones. When the DNA from cancers cells was added, the water retains its color. Though made of gold, the particles turn the water pink.

Co-author Dr. Laura Carrascosa said: "There's been a big hunt to find whether there is some distinct DNA signature that is just in the cancer and not in the rest of the body".

The test described in Nature Communications exploits the differences between the DNA in cancerous and healthy cells to allow for a quick, early diagnosis.

The test, led by Matt Trau, has been run on 200 human cancer samples and healthy DNA already, making it a reliable marker for cancer universally and an accessible technology, replacing the complicated lab-based equipment like DNA sequencing.

It's also attractive "as a very accessible and low-cost technology that does not require complicated lab-based equipment like DNA sequencing", he said. Currently, biopsy of the suspected tumour is the only confirmative test for canmcer detection. But considering the results, he noted it could be helpful in detecting cancer easily, rather than conducting invasive procedures. "If cancer is detected early, 80% patients can be cured of the disease", said a senior AIIMS doctor. "When cancer happens, the tree loses most of its decoration".

Such a test has been devised by researchers from the University of Queensland's Australian Institute for Bioengineering and Nanotechnology (AIBN). Even so, the researchers managed to identify a unique DNA nanostructure which is common to all types of cancer.
