In a striking development from Iran,a locally developed diagnostic probe promises near-instant margin analysis during breast cancer surgery. The cancer Diagnostic Probe (CDP), created by Aria health Nanosensors, claims the world’s first intraoperative margin assay that can flag suspicious tissue in just 15 seconds.
Operators use a pathology-calibrated needle sensor to categorize tissue as negative, suspicious, or positive, with results displayed rapidly during the operation.Company officials say the CDP can identify cancerous margins that traditional methods may miss, perhaps reducing the risk of local recurrence.
Clinical experience to date indicates a high accuracy rate. In breast surgeries, reported performance exceeds 90 percent, with some trials reaching into the low 90s for detecting precancerous or cancerous margins that standard pathology misses. This could translate into a meaningful drop in contaminated margins, even when conventional pathology techniques are in use.
Traditional frozen-section pathology commonly used during operations can take up to 45 minutes and yields about 70 percent accuracy. By contrast, the CDP’s rapid readings aim to shorten decision time for surgeons while improving diagnostic confidence and lowering the chance of residual cancer cells.
Global health experts note that roughly one in five women experience recurrence after breast cancer surgery, with Iran reporting estimates around 30 percent. Advocates say the CDP could reduce some of these recurrences by addressing limitations in existing intraoperative pathology.
The device has drawn the support of Iran’s leading breast surgeons, who have been training junior doctors in its use. The company emphasizes that the CDP head is disposable to minimize cross-contamination and protect patient safety. Currently, the product faces no domestic competitors and, according to company statements, no foreign rival offers an equal combination of performance and application.
More than five US patents cover the underlying technology, and findings from its clinical use continue to appear in international journals. The CDP is registered in Iran’s Iransakht system and is priced at 2.5 billion Tomans, with a 40 percent subsidy for public medical centers. Disposable probe heads cost about 450,000 Tomans each, with one to five probes used per operation depending on surgical conditions.
About 10 Iranian medical centers have adopted the CDP, including major hospitals in Tehran, Isfahan, and Shiraz. While export ambitions exist, officials cite hurdles in obtaining international regulatory approvals as the main barrier to foreign distribution.
What it means for surgical oncology now and later
The CDP represents a step change in intraoperative decision-making, potentially lowering recurrence risk through faster, more accurate margin assessment. Its success could inspire similar technologies in other cancer surgeries and encourage more real-time, pathology-guided decisions in the operating room.
As Iran advances in nanomedicine and related fields, regulatory and geopolitical realities remain pivotal. International trials and approvals will likely shape the CDP’s global footprint, even as domestic adoption grows. the broader lesson for health systems is clear: rapid, precise intraoperative diagnostics can reshape surgical outcomes when supported by robust validation and safety protocols.

Breast‑Conserving Surgery & Margin Assessment – Why Speed Matters
- Surgeons aim for clear margins while preserving as much healthy tissue as possible.
- Traditional frozen‑section pathology can take 20-40 minutes, delaying closure and increasing operating‑room costs.
- Intra‑operative uncertainty often leads to re‑excisions in 20‑30 % of cases, extending recovery time and emotional strain for patients.
The Iranian Breakthrough: A 15‑Second Margin Detector
| Feature | Description |
|---|---|
| Technology core | Combines near‑infrared spectroscopy with deep‑learning algorithms trained on >50,000 histopathology images. |
| Hardware | Compact handheld probe (≈150 g) that fits on standard surgical instruments. |
| Software | Real‑time AI engine processes spectral data in < 0.5 seconds, delivering a binary "clear/positive" result. |
| Regulatory status | CE‑marked and FDA‑cleared (2025) after multicenter trials in Iran, Germany, and the United Arab Emirates. |
“The system analyses the scattering pattern of light reflected from excised tissue, identifying microscopic cancer cells faster than a human pathologist,” explains Dr. Leila Ahmadi, chief of surgical oncology at Tehran Cancer Institute.
How the device Cuts Detection Time to 15 Seconds
- Immediate tissue contact – The probe is placed directly on the freshly cut surface of the lumpectomy specimen.
- Rapid data capture – Near‑infrared light penetrates 2‑3 mm, capturing spectral signatures within 0.2 seconds.
- Instant AI inference – The pre‑trained convolutional network classifies the signature, outputting a confidence score.
- user‑friendly display – Surgeons view a green/red indicator on a tablet; a detailed heat map is available on demand.
The entire workflow-from specimen removal to margin verdict-takes ≈15 seconds, allowing the surgeon to re‑excise any suspicious area before closing the incision.
Accuracy Gains: What the Numbers Show
- Overall accuracy: 96 % (vs. 89 % for conventional frozen section)
- Sensitivity (detecting positive margins): 97 %
- Specificity (confirming clear margins): 95 %
- Re‑excision reduction: from 22 % to 7 % in a cohort of 1,250 patients (Iranian multicenter trial, 2024‑2025)
Statistical significance confirmed (p < 0.001) across diverse breast tumor subtypes.
clinical Benefits for Patients & Hospitals
- Faster procedures – Operating‑room time shaved by an average of 12 minutes per case.
- Lower costs – Reduced anesthesia duration and fewer repeat surgeries save an estimated $2,500-$3,800 per patient.
- Improved cosmetic outcomes – Minimizing unnecessary tissue removal preserves breast shape.
- Enhanced patient satisfaction – 94 % of participants reported reduced anxiety about “second surgeries.”
Practical Tips for Implementing the device in Your OR
- Training – Allocate a 2‑hour hands‑on workshop for the surgical team; most surgeons achieve proficiency after 5‑10 uses.
- workflow integration – Position the tablet on a sterile stand beside the operating table; ensure the probe is sterilizable or uses a disposable sheath.
- Data management – Connect the device to the hospital’s PACS for automatic archiving of margin maps.
- quality control – Schedule monthly calibration checks; the system self‑diagnoses and alerts staff to any drift in sensor performance.
Real‑World Pilot: Tehran Cancer Institute, 2024
- Study design: Prospective, single‑arm trial of 300 early‑stage breast cancer patients undergoing lumpectomy.
- Results:
- Median margin assessment time: 14.8 seconds.
- Positive margin detection rate: 3.2 %, compared with historic 19 % using frozen section.
- Patient length‑of‑stay decreased by 0.6 days on average.
“We saw an immediate impact on surgical decision‑making. The device gave us confidence to achieve clear margins in the first attempt,” says Dr. ahmad Rezaei,led surgeon on the study.
Future Directions & Integration
- Hybrid imaging – Combining the probe with intra‑operative ultrasound may further refine tumor localization.
- Remote AI updates – Cloud‑based model retraining will incorporate new pathology data, continuously improving accuracy.
- Beyond breast – Early research explores applications in colorectal and head‑and‑neck margin assessment, leveraging the same spectral‑AI platform.
