CancerBro, what are the investigations required to confirm the esophageal cancer diagnosis?
First investigation to be done in a person with a suspicion of esophageal cancer is upper GI endoscopy.
The next step is to do imaging to look for the involvement of other structures.
First, we will discuss the upper GI endoscopy.
As you can see in the figure, endoscopy helps us to take a biopsy from the mass, and also to do an endoscopic ultrasound, to look for the depth of mass infiltration and involvement of surrounding lymph nodes.
CT scan of thorax, and preferable abdomen should be done to look for local extention and distant spread.
Rarely, PET CT test may also be done.
In this way endoscopy, biopsy and imaging help us to diagnose as well as stage the disease.
