Screening in Gastrointestinal Malignancies-Recent Trials and Advancements.

Gastrointestinal cancers, especially colorectal cancer, represent a major health care issue. According to the data, the incidence of these cancers exceeds 50/100,000, mainly in high-income countries. Risk factors for the disease include genetic factors (i.e., Lynch syndrome) and lifestyle factors, e.g., overweight and obesity, smoking tobacco products, low-fiber diet, and low physical activity. When diagnosed early, gastrointestinal cancers can, in most cases, be effectively treated. This review focuses on the presentation of research in the area of screening and its results. It provides insights into current trends in research on methods of early cancer detection and improving screening reporting. Differing levels of screening reporting are one of the main challenges faced by researchers in this field. Research on this issue should be conducted in parallel with research on methods of early diagnosis. Finally, the development of diagnostic methods and communication with patients are important elements of public health.
