CA199 is greater than 400U/ml, the risk of cancer is higher, but it cannot be diagnosed as cancer based on this, cancer needs biopsy histopathology examination to confirm the diagnosis.
CA199 is a kind of tumor marker, which may be related to neoplastic diseases, such as pancreatic cancer, gastrointestinal tumors, etc. It may also be related to non-neoplastic diseases, such as cholecystitis, gastritis, etc. It is often significantly elevated in neoplastic diseases, and more often than not mildly elevated in non-neoplastic diseases.
CA199 may have different normal reference values in different hospitals due to different testing methods, for example, some are 0~40U/ml, some are 0~37U/ml, and the more the reference value is exceeded, the higher the probability of oncological diseases. CA199 is greater than 400U/ml which is far beyond the range of the common normal reference value, so the risk of cancer is relatively high.
Although CA199 is greater than 400U/ml, the risk of cancer is relatively high, but can not be based solely on the level of tumor markers to confirm the diagnosis of cancer, but also need to obtain the tumor tissue, diagnosis through pathological examination, so it is recommended that the patient under the guidance of the doctor to improve the examination and clarify the diagnosis.
