According to a trial led by the researchers of the Dana-Farber Cancer Institute, a new blood test has been found efficient at identifying different types of cancer with more than 99 percent accuracy.
The new blood test examines DNA that cancer cells discard into the blood when they die. The next-generation technology concentrates on DNA modifications, aka methyl groups, which are attached to DNA through a process called 'methylation.' Abnormal methylation, which is found in cancer cells, turns out to be an important tool to detect cancer.
The overall accuracy of the blood test in detecting different types of cancer was 99.4%, while 0.6% were misdiagnosed.
