Cancer indicators are more varied, mainly referring to the tumor markers that are checked by blood draws. Generally speaking, a high tumor marker may be double or several times higher than normal, which is considered high. If it is tens or hundreds of times higher, it is definitely considered high. There are some tumor markers, also known as cancer markers, that have a role in diagnosing cancer, such as the common tumor marker for primary liver cancer, AFP, which is elevated more. If the elevation is greater than 400ug/L for one month, combined with imaging tests to find liver occupying lesions, primary liver cancer can be diagnosed. In addition, pancreatic cancer indicator CA199, or glycan antigen 199, can also be used in combination with imaging to diagnose pancreatic cancer if it is elevated greater than 400 kU/L. Pancreatic cancer is usually more difficult to get the results of pathological puncture, so with the results of imaging and tumor markers, a clinical diagnosis can also be made, if it is only slightly higher, it is not certain.
