There are various tests used to diagnose esophageal cancer
• Barium swallow – Also called esophagram, the patient swallows liquid containing barium and then conducts an X – Ray. The barium covers the affected area which is visible through an X-ray and then an endoscopy is done to check whether it is cancerous or not.
• Upper endoscopy – Also called esophagus gastric duodenoscopy, where a thin flexible tube is passed through the throat while the patient is sedated. If there is any suspicious growth of cells, a biopsy is done to check whether it is cancerous or not.
• Endoscopic Ultrasound – It is often done at the time of endoscopy. The sound waves is used to determine how deep the cancer has grown and whether it has grown into nearby lymph nodes or tissues.
• Bronchoscopy – similar to endoscopy, this is done if the cancer is located in the upper part of the esophagus or if the tumor is growing in the person’s windpipe.
• CT Scan – A CT scan helps gives a 3D picture of the inside of the body by providing a cross section computerized view of the affected area. This method also helps in determining the size of the tumor as well.
