Researchers at Johns Hopkins University are actively working towards developing a novel test that can diagnose cancer in a human much before its first symptoms show up. According to the team of researchers, the blood test successfully diagnosed cancer in a majority of people suffering from breast, lung, colon, and ovarian cancer.
“Although the test has to cover a long way before actually being utilized to screen for cancer, the study provides a path to go there,” reported the team in the journal Science Translational Medicine. “A lot of enthusiasm regarding liquid biopsies is there; however, most of that is in late-stage cancer or in patients where one already knows what to look for,” stated Dr. Victor Velculescu of the Kimmel Cancer Center at Johns Hopkins University. “The most surprising result is that the team could accurately detect a large part of early-stage patients with alterations in their blood,” he added further.
The test could diagnose cancer in the blood stream of more than half of the patients, who are having the first stage of cancer. The accuracy level of this test is much higher in case of late-stage cancer; however, the aim is to detect cancer in its earliest stage, where it is easiest to treat. One of the most significant fact that come up in this study was that there was no false positive in any of the 44 people, who underwent this test but did not have cancer.
