Key Takeaways:
- A new AI-powered tool called the iKnife can diagnose endometrial cancer within seconds.
- The device analyzes tissue vapor during surgery, achieving 89% accuracy in recent trials.
- While promising, the technology destroys tissue samples, requiring confirmation through standard biopsy methods.
iKnife
Surgeons in UK hospitals are testing a groundbreaking device that could slash waiting times for cancer diagnoses. Developed by Imperial College London, the iKnife—a smart scalpel enhanced with artificial intelligence—has successfully identified endometrial cancer (the most common gynecologic cancer) in seconds during a pilot study.
How the iKnife Works
The iKnife functions like an electric scalpel but with a high-tech twist. When held near tissue, it gently heats the sample, vaporizing molecules for immediate analysis. A built-in mass spectrometer scans these vapors for signs of disrupted lipid metabolism—a hallmark of cancer cells, which rely heavily on fats to fuel rapid growth.
“Cancer cells have a metabolic ‘fingerprint’ that differs from healthy tissue,” explains Dr. Sadaf Ghaem-Maghami, a co-author of the study published in Cancers. “The iKnife detects these changes in real time, giving surgeons critical information during procedures.”
Faster Results, Faster Care
In the trial, the device analyzed over 150 endometrial biopsies from patients with suspected cancer. It correctly identified cancerous tissue with 89% sensitivity—matching the accuracy of traditional pathology but delivering results instantly. Standard methods, which involve staining slides and microscopic review, typically take 7–14 days.
“For patients, this could mean starting treatment sooner or avoiding days of anxiety while waiting for results,” says Dr. Ghaem-Maghami.
Limitations and Next Steps
The iKnife isn’t perfect. Heating tissue during analysis destroys the sample, preventing further tests on the same material. Researchers emphasize it should complement—not replace—existing diagnostics. Still, its speed could streamline care: a positive result might fast-track treatment, while a negative reading could ease concerns ahead of formal confirmation.
Why This Matters
Endometrial cancer rates are rising globally, partly linked to obesity and hormonal changes. Early detection improves outcomes, but delays in diagnosis remain a hurdle. The iKnife’s developers aim to refine its AI algorithm with more data, potentially expanding its use to ovarian, prostate, and other cancers.
What This Means For You:
While the iKnife isn’t yet widely available, its success highlights rapid advances in cancer diagnostics. If you’re undergoing testing for endometrial abnormalities, ask your care team about new technologies that might reduce wait times.

This innovation underscores a growing trend: AI tools are becoming vital “assistants” in healthcare, offering speed and precision while clinicians retain final decision-making power. As research continues, patients may soon see fewer delays between suspicion and certainty.
FAQs: The iKnife Cancer-Detecting Scalpel Explained
1. What is the iKnife?
The iKnife is an AI-enhanced surgical tool that diagnoses cancer by analyzing tissue vapor during procedures.
2. How does it detect cancer?
It heats tissue, then uses a mass spectrometer to scan vapor for cancer-linked lipid metabolism changes.
3. How accurate is it?
In trials, it detected endometrial cancer with 89% sensitivity—results are instant vs. 1–2 weeks for standard biopsies.
4. What’s the biggest advantage?
Speed: Patients get immediate preliminary results, reducing anxiety and speeding up treatment decisions.
5. Are there downsides?
Yes—it destroys tissue during testing, so traditional biopsies are still needed for confirmation.
6. Is it available now?
Not yet. It’s in pilot testing but shows promise for broader use in the future.
7. What cancers can it detect?
Currently tested on endometrial, breast, colon, and cervical cancers. Researchers aim to expand its applications.
8. Why focus on endometrial cancer?
Endometrial cancer is the most common gynecologic cancer, with rising global rates linked to obesity and hormones.
