Oncomarker of ovaries CA 125

The study of oncomarkers is one of the important diagnostic procedures for the formulation of an oncological diagnosis in the early stages of the disease. Malignant tumor cells have a more active metabolism and constantly throw into the blood certain substances, the concentration of which can make a conclusion about the presence in the body of a cancer tumor of one or another organ. These substances are called oncomarkers. For each type of tumor, they are different. So, for the diagnosis of ovarian cancer, the CA125 oncomer is used , which is a synthesizing mesothelium of peritoneum, pleura, pericardium protein. In the female body, this protein is secreted by the uterine endometrium, and depending on the phase of the cycle, its concentration in the blood changes.

4. An increase in the CA 125 level of more than 35 U / ml may be an indication of the presence of ovarian cancer.
