It is not only accurate but also noninvasive, according to scientists. It can identify 98 percent of all cancers and up to 83 percent of cancer precursors.
If it is approved by the FDA, experts say the test could be a welcome alternative to colonoscopies which require a lengthy and uncomfortable preparation.
Scientists say more testing needs to be done to confirm the findings.
