Causes of high carcinoembryonic antigen, causes of high carcinoembryonic antigen

Carcinoembryonic antigen refers to a condition in which colorectal cancer tissue can produce a glycoprotein as an antigen to cause an immune response in patients, which is called carcinoembryonic antigen; Carcinoembryonic antigen is mainly found in digestive system cancers of endodermal origin, and carcinoembryonic antigen is also present in the digestive tract tissue of normal embryos. There are data showing that trace amounts of carcinoembryonic antigen can also be present in the serum of mortals. In life, you will encounter elevated carcinoembryonic antigen, so what is the cause of elevated carcinoembryonic antigen?

What factors cause the increase in cancer embryonic resistance? These problems have attracted the attention of many patients, and the following authoritative hepatologists will introduce this knowledge to patients. Hepatologists point out:

Many people think that carcinoembryonic antigen is the carcinoembryonic antigen of liver cancer, but this familiarity is unscientific; Carcinoembryonic antigen refers to carcinoembryonic antigen, not carcinoembryonic antigen of liver cancer; The specific marker of liver cancer is called alpha-fetoprotein. So what about causes? What causes elevated carcinoembryonic antigen?

The normal reference value of carcinoembryonic antigen is that the concentration of carcinoembryonic antigen in the human body is less than 20 ng ml, which indicates that there is a tumor. Elevated carcinoembryonic antigen is mainly seen in tumors of the gastrointestinal tract such as stomach and intestines.

Experts believe that the causes of elevated carcinoembryonic antigen are common in colorectal cancer, pancreatic cancer, gastric cancer, small cell lung cancer, breast cancer, medullary thyroid cancer, etc. In addition, things like smoking, pregnancy, cardiovascular disease, diabetes, etc., can also cause elevated carcinoembryonic antigen. Tips:

The above is an introduction to the causes of elevated carcinoembryonic antigen, if you still have any questions, please communicate directly with the liver disease expert of **! Patients with elevated carcinoembryonic antigen must be taken seriously! Patients with elevated carcinoembryonic antigen should go to the hospital in time, this article recommends patients to go to the hospital liver disease center, hospital liver disease center, advanced and complete medical equipment, has invested heavily in the introduction of international advanced testing equipment from Germany, has more than ten liver disease experts with rich clinical experience in liver disease, can provide a full range of systematic liver disease patients **.

At present, nearly 10,000 patients with liver disease have gone from the hospital to **! It is recommended that the majority of patients visit the hospital.

Hello friends, the following elaboration is for reference, if you do not understand or need to ask for details, please hi me, if you are satisfied with my answer.

Gastric, colorectal, pancreatic, and gallbladder tumors have a good positive detection rate, and can also be used as an auxiliary diagnostic index for malignant tumors such as lung cancer and breast cancer. Because there can be crossover between benign and malignant diseases, it has a certain effect on its specificity, but benign lesions are generally only temporarily low-increased. It can also be used as a general follow-up indicator for cancer patients.

The specific clinical implications of CEA are:

1. Elevated CEA is mainly seen in colon cancer, rectal cancer, pancreatic cancer, gastric cancer, liver cancer, lung cancer, breast cancer, and other malignant tumors also have varying degrees of positive rates.

2. Continuous follow-up testing can be used for the observation of the efficacy and prognosis after the operation of malignant tumors, and can also be used for the observation of the efficacy of chemotherapy patients. In general, serum CEA concentrations decrease when the condition improves and increase when the disease worsens. For patients with complete surgical resection, CEA generally returns to normal 6 weeks after surgery.

3. Intestinal diverticulum, rectal polyps, colitis, liver cirrhosis, hepatitis and lung diseases (such as emphysema, bronchial asthma) CEA also increased to varying degrees, but the positive rate was low.

of non-smokers cea 5ug l, smokers about 5ug l.

5. Abnormal kidney function can also rise slightly.

In addition, the information you provided "PET-CT has also been done, and no signs of tumor was found", it is not too likely to consider the tumor based on this mild increase in CEA alone (but it cannot be ruled out), and it is recommended that you combine the laboratory tests of other tumor markers (alpha-fetoprotein AFP, cancer antigen 125 (CA125, glycan antigen 19-9 (CA19-9, etc.) and other diseases (such as enteritis, hepatitis, emphysema, bronchial asthma) to make a comprehensive judgment.

In addition, the level of CEA content is affected by the disease and changes, is a reflection of the body's disease of an external indicator, if it is really a very serious disease caused by the increase in CEA content and only rely on what you think of "what drugs and health products can reduce carcinoembryonic antigen index" This approach can not solve the actual problem (just like the severe pain caused by some diseases, taking painkillers can reduce pain and relieve symptoms, but it cannot be a fundamental disease. It's the same as you think.)

Hello friends, the above elaboration is for reference, good luck, if you don't understand or need to ask for details, please hi me, if you are satisfied with my answer.

May be malignant.

Elevated carcinoembryonic antigen is common in colorectal cancer, pancreatic cancer, gastric cancer, small cell lung cancer, breast cancer, medullary thyroid cancer, etc.

In addition, there is a clear relationship between serum carcinoembryonic antigen levels and the stage of colorectal cancer, and the more advanced the lesions, the higher the carcinoembryonic antigen concentration.

This one is especially noteworthy. Elevated serum carcinoembryonic antigen is mainly seen in colorectal, gastric, liver, lung, pancreatic, breast, ovarian, uterine and cervical cancer, urinary tract tumors, etc. Other malignancies also have varying degrees of positive detection rates.

May be some of the most common conditions.

Smoking, pregnancy and cardiovascular diseases, diabetes, non-specific colitis and other diseases, 15% to 53% of patients will also have elevated serum carcinoembryonic antigen, so carcinoembryonic antigen is not a specific marker of malignant tumors, and only has auxiliary value in diagnosis.

May be a benign condition.

Carcinoembryonic antigen (CEA) may also be elevated in certain benign diseases, such as cirrhosis, hepatitis, emphysema, intestinal diverticulum, rectal polyps, and colitis. High carcinoembryonic antigen indicates that cancer cells are very active, and a combination of systemic chemotherapy and traditional Chinese medicine can be adopted, and chemotherapy can act quickly on the whole body, and the effect is better in the near future. However, chemotherapy is also very toxic and will bring great pain to patients, so it is necessary to cooperate with traditional Chinese medicine at the same time, which has the effect of strengthening the body, replenishing qi and nourishing blood, which can improve the body's immunity, improve circulation, alleviate chemotherapy toxicity, reduce patients' pain, and improve the quality of life.

First of all, don't worry too much. According to the doctor's diagnosis, as long as the carcinoembryonic antigen is high and does not exceed 20mg ml, it is impossible to determine the possibility that it must be cancer.

Secondly, you can do a specific part of the examination again. Although high carcinoembryonic antigen is not necessarily cancer, it may also cause inflammation, so it must not be underestimated. Generally speaking, the sooner you seek medical attention**, the better the results.

Finally, strengthen the body's workouts. Many diseases can be abandoned, and exercise can not only regulate the mood, but also strengthen the physique, which is of great help to the disease.

The significance of carcinoembryonic antigen is that it can reflect the existence of a variety of tumors, and can be used for the efficacy judgment, disease development, monitoring and prognosis estimation of colorectal cancer, breast cancer and lung cancer, but its specificity is not strong, the sensitivity is not high, and the early diagnosis of tumors is not obvious.

1.Go to the hospital for a comprehensive cancer check-up;

2.dynamic monitoring of carcinoembryonic antigen;

3.Ask an oncologist for a physical examination and thorough analysis of the results.

Question 1: What causes the high carcinoembryonic antigen index? You mean CEA, how tall?

Is it male or female? If it is only 1 5 units higher than the normal value, it may be caused by inflammation, but if it is much higher, then it is still necessary to be vigilant For men, high CEA, it is recommended to do a digestive tract examination to rule out digestive tract tumors such as rectal cancer; For women, it is recommended to do lung examination, CT and other examinations to rule out the occurrence of lung tumors.

Oh. Question 2: The reason for the high carcinoembryonic antigen Hello, it doesn't matter, because the examination of tumor indicators is mainly a screening, unless it is a substantial increase, Chen five times or more than ten times the growth, then it is a problem, it is recommended to recheck again after three months, the problem is not big, problem 3: the reason for more than 500 carcinoembryonic antigen More than 500 carcinoembryonic antigen can be said to be a serious increase in tumor indicators. It basically indicates the presence of cancer in the body!

CEA is a glycoprotein first found in the serum of colon cancer patients, and can also be detected in the serum of the fetus at 3 to 6 months, so it is called carcinoembryonic antigen. Normal reference value: serum 5ug l.

Clinical significance: Elevated serum CEA is mainly seen in colon cancer, rectal cancer, pancreatic cancer, gastric cancer, liver cancer, lung cancer, breast cancer, etc., and other malignant tumors also have varying degrees of positive rates. In general, the serum CEA concentration decreases when the condition improves and increases when the condition worsens.

Intestinal diverticulitis, rectal polyps, colitis, cirrhosis, hepatitis, and pulmonary disease are elevated to varying degrees, but the percentage of positive cases is low. 98 of non-smoking healthy people have a serum of 5ug l. About 39% of smokers cea 5ug l.

Tumor markers refer to a class of substances that are synthesized and released by tumor cells or produced by the body in response to tumor cells during the occurrence and development of tumors. When a tumor develops in the body, certain tumor markers in the blood, cells, tissues, or fluids may be elevated.

But not exactly hooked. In general, if it is mildly elevated (not too much longer than the normal reference value), the possibility of developing a tumor is relatively low, and further examination or dynamic observation can be considered, not too nervous, but not taken lightly. It can be said that there is a certain early warning effect.

Significant elevation can be used as one of the important reference factors for tumor development.

Question 4: What is the reason for the high CEA? It may or may not be caused by other diseases.

Further tests are required to confirm the diagnosis**. It is recommended to eat more fresh vegetables and fruits, drink more water, avoid spicy food, pay attention to rest, supplement multivitamins, and enhance resistance in the morning**.

What causes a high carcinoembryonic antigen index?

You mean CEA, how tall? Is it male or female? If it is only 1 5 units higher than the normal value, it may be caused by inflammation, but if it is much higher, then it is still necessary to be vigilant For men, high CEA, it is recommended to do a digestive tract examination to rule out digestive tract tumors such as rectal cancer; For women, it is recommended to do lung examination, CT and other examinations to rule out the occurrence of lung tumors.

Oh. What causes high carcinoembryonic antigen? [High carcinoembryonic antigen during physical examination] CEA is a little higher than the normal reference, and there is no diagnosis and treatment value at present, but because CEA is a tumor marker, it cannot be ignored, and it must be re-examined later, in general, the following non-malignant diseases:

Hepatitis, alcoholic cirrhosis, pancreatitis, enteritis, pneumonia, etc., can cause a slight increase in CEA, but it will not continue to rise, but malignant diseases will continue to increase, so it is necessary to recheck and compare the results with the previous one. Uric acid is high, easy to form gout, need to pay attention to diet, drink less or no beer, and eat less seafood and soy products. A slight increase in aminotransferases may be associated with mild fatty liver disease, viral infection, and is not a big problem.

Dr. Chen Lixia of Xuzhou Hospital of Traditional Chinese Medicine solemnly reminded that because the patient cannot be seen face-to-face and cannot fully understand the condition, the above suggestions are for reference only, and the specific diagnosis and treatment must be carried out in the hospital under the guidance of the doctor! ）
