Question: are esophageal tumors always malignant?
Answer: Non-cancerous tumours and conditions of the esophagus. A non-cancerous, or benign, tumour of the esophagus is a growth that does not invade or destroy normal cells and does not spread (metastasize) to other parts of the body. A non-cancerous condition is a change to esophagus cells, but it is not cancer.
