Esophageal cancer can be diagnosed through CT, gastroscopy, esophagoscopy, pathological biopsy and hematological examination, among which pathological biopsy is the gold standard for diagnosis.
1. CT: esophageal wall thickening, proximal esophageal dilatation, mostly combined with mediastinal lymph node enlargement and fibrous hyperplasia, CT can also determine whether there are metastases to other organs, which is important for the diagnosis of esophageal cancer staging.
2. Gastroscopy: Gastroscopy is an important examination method for esophageal cancer. Gastroscopy can directly observe the morphology of esophagus, see the bulging tumors and surface ulcers in the lumen of esophagus, and conduct biopsy to further clarify the pathological diagnosis, and early identification of pathological diagnosis type can provide basis for the next diagnosis and treatment.
3. Esophagoscopy: the diagnosis of esophageal cancer can also be confirmed by esophagoscopy. Patients with esophageal cancer can undergo esophagoscopy in early and middle stages.
4. Hematological examination: patients with esophageal cancer may have elevated tumor markers such as carcinoembryonic antigen, etc., and anemia may appear in blood routine results, etc. However, the indicators of hematological examination are not specific and can only be used as an auxiliary diagnosis means.
Esophageal cancer can be judged by the above examinations. If pathologically diagnosed as esophageal cancer, it is recommended to consult the doctor in time and carry out standardized and individualized treatment under the doctor’s guidance in order to prolong the survival and improve the prognosis.
