Hi, Thanks for writing in. Cancer of the esophagus is a condition that causes obstruction to food passage. In your aunty there is probably a malignant mass in the esophageal wall that is causing limitation to the swallowing of solid food. In this condition there are few ways by which she can be helped. After evaluating the malignant stricture, a metallic stent can be put in the esophagus. This works in many people but the risk of subsequent block persists. This will again cause a block to food. The other option is inserting nasogastric tune and this is something they must have done. The food is made in to viscous consistency and then given using a syringe. Th third way is operating and introducing a feeding gastrostomy. In this method the food goes directly in to the stomach and there is no requirement to feed by mouth. She can continue taking sips of water. These methods are put in to practice after evaluating patient needs and different cancer treatment institutes follow their own methods to support patient nutrition in cancer of esophagus. Please do not worry.
