Early detection is the most important strategy for controlling and management of cancer, which can significantly increase the survival rate by detecting disease in the early stages and rapid treating and preventing the progression of the disease. Based on existence of specific cell frequencies in the form of the response of each cell to its own specific frequency and the difference between normal and tumor cell frequency levels as a hallmark for cancer detection, we suggest using Graphene-based metasurfaces. Owing to the outstanding physical properties of graphene, its biosensing applications implemented by the terahertz metasurface are widely concerned and studied.a novel design of the graphene metasurface, proposed by ( Tan et al., 12) consists of an individual graphene ring and an Hshaped graphene structure. The graphene metasurface exhibits a dual-resonance response, whose resonance frequency strongly varies with its geometrical parameters. The simulated results clearly show that the theoretical sensitivity, figure of merit, and quantity of the proposed graphene metasurface for breast cells reach 1.21 THz/RIU, 2.75 RIU-1, and 2.43, respectively. These findings may open up new avenues for promising applications in the diagnosis of cancers.

The potential connection between consumption of red meat and development of colorectal cancer has been the subject of scientific discussion for a long time. However, uncertainty persists to this day. Consumption of processed meat and red meat may play a role in colon carcinogenesis, among other risk factors. An analysis of the updated data demonstrates an ever-smaller connection between red meat consumption and colorectal cancer incidence.

In this article studies of radiation radon characteristics of sites for the construction of the Volgograd region are presented. The regularities of radon distribution at the objects of the construction complex were established, depending on the influence of various factors. The studies made it possible to calculate the average annual effective equivalent doses to the population of the Volgograd Region caused by radon and daughter decay products.

This article provides studies of radiation (radon) characteristics of premises in the Volgograd Region. The purpose of the study was to identify factors of the radiation background caused by radon in civil engineering objects. The regularities of radon distribution at the objects of the building complex are determined depending on the influence of various factors. The studies made it possible to calculate the average annual effective equivalent doses of exposure to the population of the Volgograd Region caused by radon and daughter products of decay.

Depression in an article is concerning in cancer patients, It makes the clinical picture of the cancer patients more complex, more difficult to be treated and it increases the risk of death, However, In conclusion, the rate of depression in cancer patients was 70%, There was an association between moderate depression and gender, between mild depression and cancer stage, between severe depression and difficulty in paying hospital fee, In addition, patients have a lot of desires in order to improve the quality of treatment at the hospital.

The results allow to include colposcopy-uterine cytology (by histological indications), bacteriological and direct microscopic studies (if indicated by PCR – polymerase chain reaction) in the observation of pregnant women with abnormal cervical pathology. The ultrasound reveals not only pregnancy but also the prevalence of associated cervical and endometrial pathology, ovarian and helps to estimate the condition of the endometium, myometrium, bacteriological examination, diagnostics and to make correction on time with subsequent follow-up observation of the patients prior to delivery.

Oncological diseases each year are detected in a growing number of both adults and children of the Russian population. This disease is widespread, however, Russia occupies a leading place in the list of detected cases of Oncology. Cancer is poorly expensive treatment, and the mortality rate is much higher than the level of a fully cured. This problem requires a lot of attention and health services, and most of the population to their own health and life.

Based on patterns of tumor growth and its manifestations developed visual clinical symptoms at different localizations, whose knowledge allows the student and General practitioners through the «prism» of «system signals» more deliberately to grasp the educational material presented in the textbook and practically to solve the problem of early detection of tumor diseases and previous pathological processes. Our more than 20 years of experience in the use of this approach in Oncology, demonstrates the effectiveness of increasing cancer awareness and alertness of General practitioners.

The estimation of the prevalence of gastric cancer in the Primorsky Territory. As a mathematical tool used by database processing information and entropy analysis. It was found that the incidence of gastric cancer incidence in the Primorye Territory has environmental and social conditioning, with some advantage anthropogenic impacts, especially pollution of the environment and the general decline in the quality of life of the population.
