Scientists have developed what they call an "intelligent knife,” a surgical instrument that tells doctors immediately if the tissue they are cutting is cancerous.
Researchers in London tested the iKnife...and found it to be 100-percent accurate.
It works by analyzing the smoke from vaporized tissue so the surgeons know instantly if it is healthy or cancerous.
