Breast cancer (BC) is a serious threat to the health and lives of women of all ages worldwide. The overwhelming majority of deaths from breast cancer are associated with late diagnosis. Thus, the most important task of a doctor in diagnosing breast cancer is to detect the disease at its initial stage. It is known that at the beginning of the disease there can be no clinical manifestations. Because of this, there is a necessity of annual examination, first of all, for women having risk factors. It is known that timely diagnostics can stop the development of the tumor even before it begins to metastasize to lymph nodes and internal organs. Thus, the current tendency requires development and implementation of new approaches to early detection and timely treatment of BC. Among the list of new technologies for early screening there is the development of portable home “smart” mammograph “Tiskrin”. Our clinical research with 198 women showed high sensitivity and specificity of our device. The proposed method is absolutely harmless and informative and can be used any number of times regardless of the age and presence of pregnancy. Similar data on high safety make Tiscreen a widely used prophylactic agent both for early diagnostics and for determination of the risk group in women with breast cancer. The methodology we offer is simple and available for any user. No special preparation for breast examinations is required. We hope that our development will contribute to a reduction in the number of late diagnoses of the disease and increase life expectancy of women around the world.
