Frequent belching
The process of expelling oxygen from the body through belching. In general, belching is a healthy process because it expels the air that has been ingested. However, excessive belching can be a sign of cancer. Due to the tumor and the excessive bacteria that causes ulcers, severe belching may result from gastric inflammation. One of the earliest indicators of gastric cancer is excessive belching. Typically, belching occurs following meals.
