The reason for the increase in tumor marker value

Tumor markers' values of the tumor-related, but not equal to the diagnosis of cancer! "The diagnosis of the tumor must be determined by the pathological examination.We see the physical examination of the tumor markers increased the value of not too panic, there may be a transient increase in the cause of tumor markers increased the main reason There are five:

1, malignant tumor patients: the general tumor marker content will be significantly increased. But not all malignancies can cause elevated tumor markers. For example, the primary liver cancer, primary hepatocellular carcinoma patients with alpha-fetoprotein (AFP) the vast majority will be significantly increased, but the primary cholangiocarcinoma patients with AFP content is rarely elevated The This is based on the specificity and sensitivity of tumor markers to decide.

2, the normal population: Although the tumor markers are produced by the tumor, but the tumor markers in normal tissue or benign lesions can also be produced, but the proportion of such people is low and there are individual differences. This group of people should also attach importance to tumor markers, the increase in the value may be inflammation or a slight increase in cancer cells.

3, sample storage problem: improper storage of blood samples can also lead to elevated tumor markers. Such as containers, anticoagulants, preservation solution and cold chain storage and other problems, will lead to the sample can not accurately reflect the actual situation of the examiner, there may be the value of tumor markers increased.

4, the use of drugs: such as thymosin, rabies vaccine and other biological agents after use, may cause some indicators of tumor markers increased.

5, special circumstances: such as drinking, sleep is not good, there is too frequent eating supplements. For women, in the pregnancy or menstrual period before and after the blood, will be due to personal differences in physical fluctuations.

Abnormal tumor markers need to do further imaging studies

In general, the physical examination report is mainly the tumor marker detection value and the normal reference value to do comparison, if there is a very significant increase, of course, the suspicious degree of cancer will increase accordingly, for the emergence of such patients, L recommended that the next step to do a comprehensive inspection, including CT, B super, even if the slight excessive, can not be ignored, in order to completely eliminate the possibility of early cancer, but also need to go to the hospital for a month or two for re-examination , If continued to rise, we must suspect that cancer in the development, if there has been no significant increase in general benign lesions may be organ inflammation.

For cancer surgery found that tumor markers were significantly higher than before surgery, we must consider the possibility of recurrence, should promptly ask the doctor to read, do further examination to determine whether the recurrence.
