Can carcinoembryonic antigen cause cancer normally

Carcinoembryonic antigen (CEA) is a common tumor marker, but it is not a specific marker of cancer. CEA elevation is common in malignant tumors such as colorectal cancer, gastric cancer, pancreatic cancer, and lung cancer, but can also be seen in some benign diseases such as inflammation, cirrhosis, etc. In addition, some early cancers or tumors are small in size, and CEA may be normal. Therefore, if cancer is suspected, a thorough examination, including imaging, is required.(such as B ultrasound, CT, MRI, etc.), endoscopic examination (such as gastroscopy, colonoscopy, etc.), pathological biopsy, etc., to make a clear diagnosis. At the same time, doctors will also make comprehensive judgments based on the patient's symptoms, signs, family history, etc. For some high-risk groups, such as long-term smokers, those with a family history of cancer, those with chronic inflammatory bowel disease, etc., even if CEA is normal, regular anti-cancer physical examination should be carried out to detect cancer early. In short, carcinoembryonic antigen normal can not rule out cancer, need to be combined with other tests and clinical symptoms for comprehensive judgment. If there is doubt about cancer, should seek medical attention in time, for further examination and diagnosis.
