What tests can be done to confirm esophageal cancer?

Esophageal cancer is a relatively common cancer that occurs in the esophagus of the human body. In the early stages of esophageal cancer, the symptoms are not very obvious. Therefore, many patients do not discover the disease in the early stages, so they cannot receive good treatment. So, what tests can be done to confirm esophageal cancer? Let's take a closer look at this issue.

1. X-ray barium contrast

X-ray barium angiography is divided into early diagnosis and late diagnosis, and the diagnostic location and specific details are different. It is the main means of clinical diagnosis of esophageal cancer.

2. Ultrasound endoscopic examination of the esophagus

Esophageal endoscopic ultrasound (EUS) is a method that has not been widely used in the clinical diagnosis of esophageal cancer. It is based on the status of the three layers of mucosa and is expensive.

3. Esophageal exfoliative cytology examination

The esophageal exfoliative cytology examination is simple and painless for the examinee. It is the most practical method for large-scale screening in high-incidence areas. The positive rate is actually lower in late-stage cases. Contraindications of this method include hypertension, esophageal varices, and severe heart and lung diseases.

4. Fiberoptic esophagoscopy

Fiberoptic esophagoscopy greatly improves the safety and accuracy of the examination because it is flexible and allows the patient to take a free position, with good lighting and a wide viewing angle. This method is suitable for early-stage patients and confirmed benign lesions.

5. Chest CT

When diagnosing and treating esophageal cancer, chest CT or chest X-ray examination can exclude tumors in the upper respiratory tract. The sensitivity of CT in judging lymph node metastasis, the sensitivity and specificity of CT in abdominal lymph node metastasis, and the sensitivity and specificity of CT in liver metastasis are different.

The above content introduces the clinical diagnosis methods of esophageal cancer. Everyone should know these methods of diagnosing diseases. After the diagnosis, esophageal cancer patients should actively cooperate with doctors to receive professional treatment, stay away from esophageal cancer as soon as possible, and avoid more harm.
