Septin9 is a biomarker for screening colon cancer. A positive Septin9 test only indicates a higher likelihood of colorectal cancer, and cannot be used to diagnose colorectal cancer, which usually relies on the results of pathologic examinations.
The methylation level of Septin9 has a relatively close relationship with the occurrence and development of colon cancer. When Septin9 test is positive, it indicates that the patient has the gene mutation of the disease detected by the test program, and it does not indicate that the patient has already developed into cancer histologically, and it can only suggest that the examined person may be suffering from colorectal cancer, therefore, the test of Septin9 is only used for the screening of colorectal cancer, and it is not the basis for final diagnosis. Therefore, the Septin9 test is only used to screen for colorectal cancer and is not the basis for final diagnosis.
When the test result is positive for Septin9, the patient should go to the hospital in time for further colonoscopy and pathological biopsy of the suspicious tissues to avoid delaying the disease.
