Checking for esophageal cancer can be diagnosed through a combination of fiberoptic esophagoscopy, gastroscopy, CT (computed tomography), cytology and ultrasound, combined with clinical symptoms.
The most direct way to check for esophageal cancer can be done in conjunction with the doctor’s electronic gastroscopy, which can clearly observe whether there is a tumor in the esophagus during the passage of the gastroscope through the esophagus. If a tumor is found, some biopsies can be taken under the gastroscope for pathological examination to confirm whether or not there is esophageal cancer.
If available, fiberoptic esophagoscopy can also be done to confirm the diagnosis of esophageal cancer. If a tumor is found in the esophagus, some exfoliated cells or biopsies need to be taken for cytology or pathology to confirm the diagnosis of a malignant tumor.
Diagnosis of esophageal cancer can also be made by doing an upper abdominal CT examination to confirm the presence of a tumor in the esophagus through imaging methods. By observing the morphology of the tumor and combining it with clinical symptoms, the initial diagnosis of whether or not there is esophageal cancer is made. If esophageal cancer is suspected, it is also necessary to take some biopsies for pathological examination through esophagoscopy or gastroscopy to confirm the nature of the tumor.
