CA199 is more dangerous when it exceeds the normal value by several times or even higher than the normal value, which is common in digestive tract tumors. If it is mildly elevated, it may not necessarily be malignant tumor, but may be digestive tract inflammation.
CA199 normal value <37.00u/ml, mild elevation is common in gastrointestinal inflammation, such as acute pancreatitis, cholestatic cholangitis, cholelithiasis, acute hepatitis, cirrhosis of the liver and so on can also be seen in different degrees of elevation.
If it is tens or even hundreds of times lower than the normal value, it often suggests that pancreatic cancer, hepatobiliary cancer, gastric cancer, colorectal cancer and so on are very likely, among which pancreatic cancer is the most common.
However, it should be noted that tumor marker examination has limitations, patients should not be overly alarmed, and should actively improve the relevant imaging pathology examination, and once diagnosed, actively cooperate with the treatment.
