2. Cancers are divided in to three categories, early cancer, locally advanced cancer and widespread disease. With early cancer, one can expect total cure. With locally advanced disease, occasionally cure is possible. with widespread or disseminated disease, cure is usually not possible.

5. Generally oesophageal cancer is a bad disease. However with additional treatment, there is a reasonable chance that you should be cured.
6. Oesophageal node as explained is a lymph node next to the oesophagus. Most tissues and organs in the body are surrounded by lymph nodes. These lymph nodes deal with infection.
7. You may find initially that you need to eat more frequently and take small meals and not mix food and water.
