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 DNA fingerprint appear in the case of cancerous tumors.
The test could also be performed by sampling tissue, the scientists said.
The researchers concluded that the test, which will open new perspectives in the field of early detection of the disease, after they were able to detect a "sign of vitality" refers to several types of cancer.
"One of the main advantages of this technique is that it is very cheap and very simple, so it can be adopted in the clinic very easily," said Laura Carrascoza, a researcher at the University of Queensland. "It was difficult to identify a simple sign of this complex disease. Several types need several tests.
However, researchers have found a marker that appears in all types of breast cancer, prostate cancer, colon, rectum and lymphoma, suggesting it may be a "general sign of all cancers."
The test, reported by the journal Nature Communication on Wednesday, uses a fluid that changes color with cancerous cells anywhere in the body.
Scientists have discovered that the DNA of the cancer-infected and ordinary DNA-infected organisms binds differently to minerals, acting differently in water, so scientists added small particles of gold to the water, turning the liquid into pink.
If the DNA of the cancer is dropped into the water, it attaches to the metal molecules and the water remains the same color, but the normal (healthy) DNA attaches to the gold in a different way, turning the color of the 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.
