Blood Test May Detect Multiple Cancer Types: Study
-
A new blood test for cancer was highly accurate in detecting more than 50 types of cancer, and also identified the tissues where the cancer originated, say researchers. The test (developed by Grail) uses next-generation sequencing to analyze the arrangement of methyl groups on circulating cell-free DNA in a blood sample.

@pritha a researcher not involved with the study suggests the results may be overly optimistic and show higher sensitivity and specificity than are likely to be seen in follow-up studies.
