Cancer treatment could be administered in the early stages of the onset of the disease thanks to a new diagnostic technique published in the August issue of Genome Research.
Scientists at Johns Hopkins have developed a very sensitive test that uses nanotechnology to detect the earliest signs of DNA changes, which could be a sign of eventual cancer.
The test has been developed over the past three years and examines minute crystals known as quantum dots.
Jeff Tza-Huei Wang, associate professor of mechanical engineering at the John Hopkins Kimmel Cancer Centre, led the study and commented: "If it leads to early detection of cancer this test could have huge clinical implications.
"Doctors usually have the greatest success in fighting cancer if they can treat it in its early stage."
In other news, a recent study by Cancer Research has found that the rate of death among cancer patients has been falling over the past 30 years.
