A new blood test touted as so sensitive it can spot one cancer cell among billions of healthy ones has the medical community buzzing. Oregon Health Science University Pathology Professor, Dr. George Thomas, is excited by the future possibilities of the test that might be able to look at those cancer cells and tell if there are specific mutations And in terms of treatment, if there are specific drugs that target these mutations, then you can perhaps add them into the mix. Four big cancer centers will begin studies on the new test this year. Dr. Thomas says he doesn't know if OHSU will be part of that, but he is excited to see the results.
