Abstract
Since ColoRectal Cancer (CRC) remains the third cause of cancer death in the world, a better understanding of the reasons underlying poor adherence to and delay in undergoing CRC screening programs is important.CRC screening decision-making process can be conceptualized as the relationship between intention and behavior and needs to be investigated including the impact on patients’ decision of a broad range of psychological factors and personal predisposition as fear of a positive screening test, poor understanding of the procedure, psychological distress, anxiety, anticipation of pain, feelings of embarrassment and vulnerability. Also socioeconomic, ethnic and sociological influences, and organizational barriers have been identified as factors influencing CRC screening adherence. Decision-making process can finally be influenced by the healthcare background in which the intervention is promoted and screening programs are carried out.However, there is still a gap on the scientific knowledge about the influences of diverse elements on screening adherence and this deserves further investigations in order to carry out more focused and effective prevention programs.

The options currently offered for CRC screening include Fecal Occult Blood Test (FOBT), Flexible Sigmoidoscopy (FS), Optical Colonoscopy (OC) and the recently proposed CT Colonography (CTC)
We carried out a computerized search on Google and PubMed database combining the search terms “cancer screening”, “compliance barriers” and “colorectal cancer” to assess studies that have tried to identify the main adherence barriers to CRC screening programs
Summary
Its incidence and mortality have decreased over the past 20 years, ColoRectal Cancer (CRC) remains one of the leading causes of mortality and morbidity in the world [1, 2]. The options currently offered for CRC screening include Fecal Occult Blood Test (FOBT), Flexible Sigmoidoscopy (FS), Optical Colonoscopy (OC) and the recently proposed CT Colonography (CTC). FOBT is probably the least expensive screening test and is well accepted with participation rates of 48% to 63%. It has some limitations, such as the need to repeat the test every one/two years and the low sensitivity for large adenomas (≥10 mm) [7]. In spite of being the most complete diagnostic test for CRC and colorectal adenomas, OC shows low acceptance as a screening test. We carried out a computerized search on Google and PubMed database combining the search terms “cancer screening”, “compliance barriers” and “colorectal cancer” to assess studies that have tried to identify the main adherence barriers to CRC screening programs
