Australian researchers have developed a revolutionary 10-minute test to diagnose cancer, which can help early detection and treatment, possibly several years before the onset of symptoms.
Researchers at the University of Queensland in Australia have revealed a new blood test that can detect cancer in the body in just 10 minutes and depends on the discovery of a DNA fingerprint that appears in cancerous tumors.
The test could also be done by taking tissue, the scientists said.
The researchers discovered that the test, which would open up new prospects for early detection of the disease, has revealed a "biomarker" referring to several types of cancer.
"It was difficult to identify a simple sign of this complex disease," said researcher Matt Trouw. "Even a disease, such as breast cancer, has several types that require multiple tests.
However, the researchers found a marker that appears in all types of breast cancer, prostate cancer, colon, rectum and lymphoma, suggesting that it could be a "general sign" of all cancers ".
The test, reported by Nature Communication on Wednesday, uses a fluid that changes color with cancer cells anywhere in the body.
Scientists have discovered that the DNA of cancer-infected organisms and common organisms infected with DNA binds differently to minerals, acting differently in water. The scientists therefore added small particles of gold to the water, making the liquid pink.
If the cancer DNA falls into the water, it attaches to the metal molecules and the water stays the same color, but the normal (healthy) DNA binds to gold in a different way, turning the color of water into blue.
It is expected that this test will be used, along with other periodic tests conducted by patients, such as measuring the proportion of cholesterol in the body.
Researchers work with UniQuest, a commercial company, to develop and possibly license their results.
In addition, the grant allowed the National Breast Cancer Research Foundation to promote the diagnosis of cancer.
