More than a century has passed since the discovery of terahertz (THz) radiation and the first experience in biology and medicine [1]. However, biomedical application of THz radiation is still an actively developing field of knowledge. Terahertz spectroscopy has shown great potential in biomedical research due to its unique features, such as the non-invasive and label-free identification of biological samples and medical imaging [2]. The report will provide a review of the known data and our own studies on THz spectroscopy of blood for diabetes [3], thyroid [4] and liver cancer [5] diagnosis. We will discuss applications of machine learning techniques to THz spectroscopy data, which will help to advance the method into clinical practice [6-8]. We will demonstrate the unique capabilities of THz radiation in the diagnosis of benign and malignant neoplasms of different nosology and localization [2,9], diabetic foot [10] and in ophthalmology [11]. We also highlight the biological effects of THz radiation and establishment of safe doses [12]. Further development of biomedical application of THz radiation is impossible without creation convenient and cheaper THz devices, super-resolution THz optical systems, THz waveguide. In conclusion, the most promising directions of further biomedical application of THz radiation are formulated.
