Early testing of new blood cancer screening shows some promise
Scientists announced Thursday in the journal Science that they've developed a highly specific blood test that screens for 8 common cancer types, helps identify the location of the cancer, and is expected to cost about $500.
Why it matters: The research community is searching for a non-invasive way to screen for cancer but has faced huge problems of high costs and false positives — which can cause a patient unnecessary testing and anxiety.
Yes, but: The study was conducted in a relatively small number of cancer patients. Some scientists believe the high specificity and sensitivity rates of the CancerSEEK test may drop in a larger patient group and say they will be watching the results from a larger trial expected in about 18 months.
