What tests are used to diagnose esophageal cancer?

Ordinary esophageal cancer patients need to undergo CT, gastroscopy, esophagoscopy and other examinations to confirm the diagnosis.

1. CT: CT scans usually show thickening of the esophageal wall and dilatation of the proximal esophagus, most of which are combined with mediastinal lymph nodes and fibrosis. CT can also determine whether other organs have metastasized, and plays an important role in the staging diagnosis of esophageal cancer.

2. Gastroscopy: Gastroscopy is an important examination method for esophageal cancer. Gastroscopy can directly observe the shape of the esophagus, see the protruding tumors and surface ulcers in the esophageal cavity, and perform biopsies to further clarify the pathological diagnosis. Early identification of the pathological diagnosis type can provide a basis for the next step of diagnosis and treatment.

3. Esophagoscopy: Esophagoscopy can also be used to diagnose esophageal cancer. Esophagoscopy is used to check whether there are space-occupying lesions or ulcer lesions in the esophagus, and then a pathological biopsy is performed to confirm the diagnosis. Esophageal cancer patients can undergo esophagoscopy in the early and middle stages.

It is recommended that patients should receive treatment as soon as possible after diagnosis, which can prolong survival time and improve prognosis.
