Early diagnosis of esophageal cancer is very important. Patients need periodic health check-ups, screening in subjects at high risk of this disease. When there are any suspicious signs, patients should immediately go to specialized facilities for examination and early diagnosis. The diagnosis of esophageal cancer is based on the symptoms of the disease combined with an X-ray of the esophagus and other tests. For an early and accurate diagnosis of this disease, patients need to undergo endoscopy combined with ultrasound and biopsy.
X-ray: X-ray of the esophagus should be done in the supine position. When performing this method, it is possible to see a hard image of the esophagus or a narrow image of the esophageal lumen, which can be seen as a tumor. Density tomography method: this method helps in early diagnosis and higher accuracy than X-ray, especially when cancer cells have spread into the esophageal wall. In addition, density tomography also detects metastases into the mediastinum. Perform endoscopy: Esophageal endoscopy with biopsy is a mandatory test in case X-ray cannot identify the disease. This method helps doctors assess the extent of the cancer and the nature of the tumor. Besides, the combination of endoscopy and combing cytology gives high cancer positive results in over 90% of cases. Performing endoscopic ultrasound: This method helps to diagnose the depth of tumor infiltrating the esophageal wall, and at the same time evaluate the invasion of cancer into the esophageal lymph nodes. The rate of people suffering from cancer is increasing, the early diagnosis of the disease will help doctors have timely treatment and reduce costs for patients. Currently, Vinmec is implementing a screening package for cancer of the gastrointestinal tract (esophagus - stomach - colon) to prevent esophageal cancer, avoiding factors that cause high cancer risk.
