A bioimpedance diagnostics device has been developed at the VSGUTU, which determines the resistance of biological tissues for given frequencies of electric current. This device allows to evaluate the state of organs and systems of biological objects under various external influences (burn, anesthesia, frostbite, etc.), as well as cancer diseases. It differs from all existing devices in that it allows you to simultaneously obtain impedance data at different frequencies of the probing current. The purpose of the study is to study skin cancer (basal cell carcinoma) using a bio-impedance diagnostic apparatus. Patients with malignant neoplasms of the skin were studied using bio-impedance spectrometry apparatus. An analysis of the comparison of impedance data in patients with skin and unaffected skin cancer showed that the impedance of the skin affected by cancer is higher at different frequencies from 50 Ohm to 86 Ohm. Those. The electrical resistance of the affected skin of the patient is increased by 1.5 to 2.1 times. Thus, the developed device bioimpedance spectrometry allows for the diagnosis of cancer.

Keywords:apparatus, electric current, resistance of biological tissues, frequency of probing current, bioimpedance diagnostics, generator, power supply.
