What Is Esophageal Cancer?
7. Complications
As mentioned, esophageal cancers are difficult to detect in the early stages because there are no obvious symptoms. This means most diagnoses occur when the cancer is already advanced. In the advanced stages, the tumors in SCC cases can be so large that they obstruct the esophagus. This can make it difficult for patients to take in any food or drink.
This obstruction can also cause pain for the patient. In adenocarcinoma cases, the sliding back of acidic digestive juices can also corrosion the lining and cause pain. This damage can also lead to bleeding that can either be slow and gradual or sporadic and severe.
