What examination is needed for high carcinoembryonic antigen

When carcinoembryonic antigen (CEA) is significantly increased, it is necessary to first ask the patient to do chest CT examination, so as to find out whether there is non small cell lung adenocarcinoma at an early stage. Secondly, the increase of carcinoembryonic antigen can also be seen in breast cancer patients, so when carcinoembryonic antigen increases in female patients, they should also go to the breast B ultrasound examination. And patients with gastric cancer and intestinal cancer can also have increased carcinoembryonic antigen, so gastroscopy and enteroscopy are necessary inspection methods for patients with increased carcinoembryonic antigen. CT or enhanced CT examination of the pancreas or MRI examination of the pancreas are very necessary for the detection of pancreatic cancer. These examinations are also one of the necessary examinations for patients with elevated carcinoembryonic antigen.
