Scientists have removed a tumor using electromagnetic radiation

Employees of the medical electronics laboratory of Novosibirsk State Technical University (NSTU) were able to remove tumors in animals using high-frequency electromagnetic radiation during an experiment.

Nowadays, radiofrequency or microwave ablation is most often used to remove tumors. During radiofrequency ablation the current flows through the patient's body, and during microwave ablation - harmful to the body microwave radiation.

Novosibirsk scientists proposed to use safer high-frequency electromagnetic radiation from 5 to 30 MHz. The method can be used for destroying both soft tissues and bones and cartilage. The radiation makes a one centimeter deep tissue incision in seven seconds.

"There is a high speed of achieving the desired result with virtually minimal impact on the surrounding tissue. In addition, the areas of coagulation of the cut edges and puncture obtained with the help of HF-destruction are relatively small in size," says Svetlana Belavskaya, Associate Professor of the Department of Electronic Devices of NSTU, Candidate of Technical Sciences.

Pilot experiments were conducted on muscle tissue biopsy of cattle and pig skin. Also preclinical tests were conducted on laboratory mice. The result showed that there is no bleeding during this surgical intervention, and the wound heals faster than with other methods.

The priority of the method was recorded in the Federal Institute of Industrial Property. The research results were published in the journals "Data Analysis and Processing Systems" and "Advances in Engineering Research" (New York, USA) and were presented at international conferences.
