"Diater" against breast cancer
St. Petersburg scientists have created a device for removing malignant tumors by ultrasound
Scientists from Peter the Great Polytechnic University together with colleagues from other universities have developed the first medical complex in Russia for non-traumatic treatment of breast cancer. The new technique does not provoke the development of new oncological diseases, and also does not cause pain to patients and does not leave scars.
Specialists of the Laboratory of Ultrasound Technologies of SPbPU have developed a medical complex "Diater", with which doctors will be able to remove tumors to patients with breast cancer without surgery. The device uses HIFU (High Intensity Focused Ultrasound) technology – focused ultrasound of high intensity.
When treating with this complex, general anesthesia is not required, since the patient does not feel pain. There are no scars left after the procedure.
According to experts, the treatment with "Diater" reduces the likelihood of cancer in healthy cells, thanks to the operational control of the degree of exposure.
"One advantage of our development is the electronic movement of the focal area of ablation. This means that the mammary gland and the therapeutic unit of the installation are connected and do not move relative to each other during the procedure. The contact spot remains constant, which improves the quality of the procedure and reduces the time of its implementation," the Committee on Science and Higher Education said.
Preclinical studies of the device were conducted jointly with the NMIC of Oncology named after Petrov and the First Medical University named after Pavlova.
Now scientists are planning to create the same device for the treatment of varicose veins and uterine fibroids, ablation (rejection of part of the tissues using radiation) of neoplasms in the thyroid gland and prostate.
