Serious Warning Signs Of Stomach Cancer

Unexplained Nausea And Vomiting

A cancerous tumor in the stomach can take up room and reduce the space available for food. This can, as mentioned, occur because the tumor impairs the mechanical action of stomach emptying and delays the movement of the food into the small intestine. This mechanism can be painful in some patients. This pain is often relieved by vomiting. Food that cannot move past the stomach can begin to ferment or undergo a chemical break down process in the absence of oxygen.

The environment created during this process is favorable for the growth of harmful bacteria, causing a patient to become nauseous and vomit. Food that sits in the stomach too long can develop into a bezoar or a hard, solid collection. Bezoars can obstruct the gastrointestinal tract, which also results in nausea and vomiting. Furthermore, bleeding from the tumor inside of a patient's stomach can cause it to become irritated and result in vomiting.
