Introduction
If the carcinoembryonic antigen (CEA) level is normal and the patient has no other discomfort symptoms, a colonoscopy is usually unnecessary, as this represents a normal physiological condition and there is no need for excessive concern. However, if CEA is normal but the patient experiences other obvious symptoms such as abdominal pain or rectal bleeding, this may indicate an underlying abnormality, and a colonoscopy may be needed to help determine the cause.
Generally, if carcinoembryonic antigen (CEA) levels are normal and there are no other discomfort symptoms, a colonoscopy is usually not necessary. However, if CEA levels are normal but the individual experiences other obvious symptoms, a colonoscopy may be needed to help identify the underlying cause and facilitate subsequent treatment. Specific analysis is as follows:
If a patient is in good health, CEA levels may appear normal during testing, and no other discomfort symptoms will occur. This is considered a normal physiological condition, and patients need not worry excessively or undergo another colonoscopy.
CEA is a marker used in screening for colorectal cancer. If a patient's CEA test results are normal but they experience obvious symptoms such as abdominal pain or rectal bleeding, this indicates an abnormal condition. In such cases, a colonoscopy should be performed under a doctor’s guidance, along with other diagnostic methods, to determine the exact cause.
Patients should maintain a calm mindset when undergoing CEA or colonoscopy examinations, avoiding excessive anxiety. After the examination, they should continue monitoring their physical symptoms and promptly communicate any discomfort to their physician.
