Carcinoembryonic antigen 7.86ng/ml of non-small cell lung cancer cannot determine the severity of the disease, and needs to be combined with the size of the tumor, lymph nodes, and metastasis of distal organs.
Carcinoembryonic antigen is only an indicator for screening and detecting non-small cell lung cancer, although 7.86ng/ml is mildly elevated, it cannot be used as a criterion for determining the severity of the disease, which needs to be determined according to CT, MRI and other examinations to see the size of the tumor, lymph nodes, and metastasis of the distal organs.
If the tumor size of non-small cell lung cancer is small and there is no lymph node or distal organ metastasis, then the condition is not serious and can be cured by radical surgery; if there are lymph node and distal organ metastasis at the same time, then the condition is relatively serious and it is more difficult to be cured.
