When surgeons remove tumor tissue they try to leave a "margin" of healthy tissue to ensure all the cancer is removed. Sometimes this means the patient has to remain under general anaesthetic for another 30 minutes or so while tissue samples are sent for analysis to check if the margin is clear. Even then, it is still possible that some cancerous tissue remains, and the patient has to undergo further surgery to remove it. Now, a new technique based on an "intelligent knife," called the "iKnife," promises to remove the need for lab analysis and the accompanying delay, and it also helps avoid repeat surgeries.
