Genetic Alterations Linked To Cancer In Some Blood Samples
...s. These results must be confirmed in much larger clinical
trials, Sidransky says. The technique used in this study was developed by Sidransky's team and first used to detect cancer cells in urine. The test uses a series of DNA markers to seek out geneticmutations specific to each patient's cancer. "We dec...
