Tumor markers are abnormal and it has a cause. So it’s just that the cause of CA125, which we’ve studied more clearly, is that inflammatory tissue stimulates the peritoneum, and that can cause an increase in CA125. Commonly, endometriosis, it is sometimes due to menstruation, ovarian tissue bleeding, because there is ectopic tissue, bleeding stimulation of the peritoneum, resulting in increased CA125. Also, pelvic inflammation can stimulate the peritoneum, ovarian tube pus, inflammation, then stimulate the peritoneum also cause CA125 increase. There is another type of disease that can also cause CA125 to increase, what is it? Liver disease, liver disease, inflammation, or abscess, it stimulates the peritoneum of the epigastrium can also cause CA125 increase. There is also ovarian cancer, which has ascites and pleural fluid, and stimulation of the pleura can also cause increased CA125. Some of them are not particularly clear, we can only know that these tumor markers are high is a high chance of a certain disease. For example, we clinically suspect teratoma, that may be CA125 and CA199 are increased, this is our clinical experience. But why CA199 is high, I don’t know, so we clinically, because we now have a very good physical examination, we all pay more attention, so many people have checked some tumor markers, so there are a lot of such patients come to see the clinic. They say, “Doctor, I’ve had high tumor markers for many years, and I don’t know what’s the reason. Some of them we didn’t find the lesion, but the patient is living well, she doesn’t have a tumor, so all these are waiting for us to study in the future.
