Normal tumor markers, no cancer?

summary

Tumor markers are a kind of substances reflecting the existence of tumor. Tumor markers also have the characteristics of high sensitivity, high organ specificity, easy operation and strong correlation with clinical development and prognosis. In the detection of blood, body fluid and tissue, the substances related to the occurrence and development of tumor can be detected. If the content in tumor tissue is much higher than that in normal tissue, and its existence or even quantitative change may indicate the existence and nature of tumor. So normal tumor markers mean no cancer? I'd like to share my views with you.

Normal tumor markers, no cancer?

First, tumor markers are normal, and it can not be ruled out that there is no tumor. Because of the specificity of some tumors, some tumor markers will not rise from beginning to end; Some tumor markers are normal in the early stage of the disease and will not rise until the disease develops to a certain extent.

Second, the diagnosis of all diseases can not only rely on the normal tumor markers, but also ignore the comprehensive diagnosis of other detection indicators. So, the diagnosis of lung cancer, in addition to tumor markers, but also need to carry out the impact of pathological examination, histopathological examination to make a comprehensive judgment, and ultimately also need to be based on histopathological examination in order to diagnose lung cancer, because only pathological examination is the gold standard of disease diagnosis.

Third: the increase of tumor markers may indicate the existence of some tumors, but it does not necessarily mean that they have tumors. For example, tumor markers are also produced in normal tissues and benign diseases, and there are individual differences. Some bad living habits such as smoking, drinking, taking some drugs and taking supplements can cause a transient increase of some tumor markers.

matters needing attention

Twelve tumor markers that can detect whether there is cancer in patients are very important for us to detect cancer early. However, some higher values do not necessarily mean cancer, there are further diagnosis. Do twelve tumor items regularly, we observe whether our body is abnormal. Once we find that there are tumor markers in our body, we should pay enough attention to them and treat them in the hospital as soon as possible.
