Can a positive carcinoembryonic antigen (CEA) test result become negative?
Disease description:
My grandfather recently underwent surgery for stomach cancer treatment. However, during a follow-up examination, his carcinoembryonic antigen (CEA) test came back positive. We are very concerned—can a positive CEA result turn negative?

Dr. Peng Xiaodong
A positive carcinoembryonic antigen (CEA) result usually does not revert to negative, as a positive CEA is generally associated with malignant diseases. Early detection and prompt treatment can improve the cure rate. In daily life, it's important to develop good living habits, maintain a calm and positive mood, and engage in appropriate outdoor exercise to enhance the body's immunity.
