Cancer has become one of the most important causes of mortality that human beings have faced in this century. Because the digestive system is a region where nutrients are involved and processed in the human body, colorectal cancer (CRC) has been increasing in recent years due to irregular and bad nutrition, stress, immobility and increased environmental pollution. Early detection has become one of the most important ways to stay alive in cancer. In recent years, artificial intelligence studies have begun to be used in the diagnosis and treatment of cancer. In this study, there is a search for early and practical diagnosis by analyzing some blood data acquisition related to colon cancer from different literatures together. Seven different biomarkers and blood-related gene data acquisition were used in the literature and WBC, CRP and CEA type may be used as biomarkers to diagnosis and follow-up for colorectal cancer.
