Iranian Scientists Develop New System for Diagnosing Breast Cancer by Electromagnetic Waves
The results of the research, titled ‘High-Frequency (30 MHz-6 GHz) Breast Tissue Characterization Stabilized by Suction Force for Intraoperative Tumor Margin Assessment’ and published in the Diagnostics magazine show that the high-frequency electromagnetic waves (30 MHz to 6 GHz) can detect breast cancer.
“We are completing the cycle of diagnosing breast cancer masses and margins before, during and after surgery in an operating room and the pathology room, and this system is a ring of this cycle,” said Mohammad Abdol Ahad, a faculty member of the Electrical and Computer Engineering department of the University of Tehran and the head of the Electronic Cancer Research Center of University of Tehran.
Abdol Ahad, who is also the inventor of the Cancer Diagnostic Probe (CDP) device which is now an approved diagnostic device during surgery and is being used in clinical centers, added, “We are making efforts to give the pathologists additional information about the location of suspected cancer tissue in a short period of time from the freshly removed tissue from the patient's body without any preparation process in order to reduce the time and cost of diagnosis in the pathology laboratory through research and using the method of electrical stimulation at gigahertz frequencies and calculating and measuring scattering parameters.”
Iran is now mass-producing and supplying medical centers with a home-made Cancer Diagnostic Probe (CDP) device for detection of surgical margins of cancerous tumors which enjoys 95% accuracy.
"CDP is the first completely Iranian cancer surgery device in the world, and so far 20 devices have been delivered to medical centers or are being delivered," said Abdol Ahad earlier this year.
Noting that the CDP is capable of identification of infected margins and involved lymph nodes during surgery with the help of electrical nanostructure sensor, he said that the CDP is the first completely Iran-made cancer surgery device in the world.
“It took 8 years since the formation and proof of the initial scientific idea based on the electrical measurement of cell metabolism to the final clinical product,” Abdol Ahad said.
He underlined that the Iran-made CDP system has several US-granted patents and more than 11 articles in prestigious international journals in various fields from bioelectronics to surgery with impact factors of above 10.
The Iran-made CDP device displays the results to the surgeon during surgery in real time.
