Scientists have been able to develop a blood test to determine in less than 10 minutes whether a cancer type is badociated with the patient.
"The test is still under development, but if it is introduced, it will be a major change in the way cancer is screened and make it easy and affordable for patients," the Sun reported.
The new method involves the use of a fluid that changes color to detect the presence of malignant cells anywhere in the body and presents the results within 10 minutes, but does not reveal the Location and extent of infection.
The test has a sensitivity of about 90%, which means that it will be able to detect 90 out of 100 cases of cancer and that doctors will then be able to perform other tests to diagnose the specific type of malignant disease and its stage.
Scientists have discovered that cancer DNA and normal DNA stuck differently to minerals and behaved differently in the water, adding small particles of gold to the water which turned the liquid into pink.If the DNA fell into the water, it bound to the metal molecules and the water remained of the same color. Normal "healthy" DNA attaches to gold in a different way, turning water into blue.
"We do not know yet if this test can diagnose all cancers, but it looks really interesting because it is incredibly simple, accessible, inexpensive and without any need," said Matt Trouw, professor of chemistry at Queensland University in Australia and leader of the team of scientists who innovated. Complex laboratory equipment such as sequencing of DNA. "
"Our technology can be an investigative tool to inform physicians that the patient may have cancer but requires further testing using other techniques to determine the type and stage of cancer," said Trouw.
Scientists are currently conducting clinical trials on patients with a wide range of cancers, where DNA in cancer cells may be filled with mutations that stimulate specific tumor growth, but these mutations tend to differ depending on the type of cancer.
