Can esophageal cancer be detected by blood draw?

1. Esophageal cancer cannot be detected by blood test and generally requires endoscopic examination and double contrast barium radiography.

2. Esophageal cancer is a malignant tumor that occurs in the esophagus and cannot usually be detected by blood draw. After esophageal cancer occurs, tumor markers will increase, but the specificity of tumor markers is not strong and cannot be completely diagnosed as esophageal cancer.

3. The main examination method for esophageal cancer is endoscopic examination, including ordinary endoscopy and ultrasonic endoscopy. Ordinary endoscopy can find red erosions and plaque-like thickening in the esophagus. If it is an ultrasonic endoscope, it can also clearly show the changes in the hierarchical structure of the esophageal wall. It can also be done through double contrast imaging of gas-barium and injection of contrast agent for X-ray examination. This is the simplest and most economical examination method for diagnosing esophageal cancer, and it can intuitively judge the location and length of esophageal cancer.

4. If diagnosed with esophageal cancer, early treatment is recommended. Surgical resection, radiotherapy, chemotherapy and other methods can be used to prolong the patient's survival. It is recommended that patients maintain a relaxed and happy mood during the treatment process and pay more attention to diet after surgery according to the doctor's advice.
