Elevated carcinoembryonic antigen after 4 months of lung adenocarcinoma surgery may be caused by infection and recurrence of lung cancer.
1. Infection, lung adenocarcinoma surgery will cause damage to patient’s body and it will take a long time to recover, during this period, immunity and resistance are relatively low, if infection occurs, it will be accompanied by mild elevation of carcinoembryonic antigen, so go to the hospital in time to get treatment under the guidance of doctor.
2. Recurrence of lung cancer, there is still a certain possibility of recurrence of lung adenocarcinoma after surgery, when the cancer cells spread or metastasize, the carcinoembryonic antigen of the patient will also increase, and the increase is obvious. At this time, it is necessary to cooperate with doctors to improve relevant examinations and take timely treatment such as surgery, radiotherapy and chemotherapy after diagnosis.
After lung adenocarcinoma surgery, it is recommended to review tumor markers regularly. When elevated tumor markers are found, don’t be alarmed, and actively cooperate with doctors to find out the causes and further treatments.
