Summary
Brief summary (as posted)
The aim of this observational study is to investigate whether computed tomography can be used as an alternative to colonoscopy in colon cancer screening. The main question the study aims to answer is: Can colon cancer screening be performed as effectively with computed tomography as with colonoscopy? Participants in the colon cancer screening group will be divided into two groups: those who underwent colonoscopy and those who underwent computed tomography. The screening effectiveness of the two methods will be compared.
