Can a blood test detect esophageal cancer?

The clinical examination and diagnosis of esophageal cancer are guided by advanced science and technology, so this is good news for patients. Patients need to have a detailed understanding of the entire examination process so that they can play a promoting role in the treatment process and live a better life. So can blood tests detect esophageal cancer?

Laboratory examination is an important basis for the diagnosis of esophageal cancer. The main examination methods include: CT scan, esophageal exfoliated cytology and X-ray barium meal examination. X-ray barium meal examination is one of the important means of diagnosing esophageal and cardia tumors. It can provide reliable data for the study of early esophageal cancer. Combining cytology and esophageal endoscopy can improve the accuracy of esophageal cancer diagnosis. X-ray barium meal examination of esophageal cancer not only determines the location, length and degree of obstruction of the lesion, but also determines whether the esophageal lesion has invaded and the scope of invasion.

For suspicious cases, double contrast X-ray of esophageal swallowing of dilute barium should be performed. In the early stage, the following can be seen: ① disordered, rough or interrupted folds of the esophageal mucosa; ② small filling defects; ③ localized rigidity of the tube wall and interrupted peristalsis; ④ small niche shadows. In the middle and late stages, there are obvious irregular stenosis and filling defects, and the tube wall is rigid. Sometimes the esophagus above the stenosis has different degrees of expansion on the oral side. B-ultrasound examination to check whether there is metastasis to the liver or other organs. Laboratory examination of anemia and carcinoembryonic antigen detection. CT examination to check whether there is metastasis to the brain, lungs, etc.

Everyone feels very sorry about the occurrence of esophageal cancer, because this ruthless disease devours people's physical health and life safety. Timely adjustments need to be made to detect the disease during the diagnosis process. Patients must also fully understand the relevant knowledge to facilitate the treatment of the disease.
