3. Esophageal cancer
The esophagus is the tube that transports the food you eat to your stomach. It makes a long journey from the stomach to the mouth, which is why the esophagus is such an important part of your body. When adenocarcinoma starts to manifest as esophageal cancer, it will begin its rampage within the mucous glands that line the lower area of your esophagus.
Some of the early symptoms of this form of adenocarcinoma will be difficulty swallowing, frequent choking, and heartburn. If you notice one or more of these symptoms, it might be due to adenocarcinoma developing in the lower area of your esophagus.
Many people shrug off these symptoms and think that it is merely due to improper chewing of their food, but they could very well be the result of underlying conditions that require immediate treatment. In the later stages of cancer, it might become impossible to eat solid food and the patient may need to rely on dextrose for nutrition.
