Stomach Cancer
What is Stomach Cancer?
Stomach cancer, also known as gastric cancer, is a type of cancer that originates in the cells lining the stomach. The stomach is a muscular organ located in the upper abdomen, and its primary function is to break down and digest food. Stomach cancer can develop when normal cells in the stomach undergo genetic mutations, leading to uncontrolled growth and the formation of a tumor.
There are several types of stomach cancer, but the most common is adenocarcinoma, which originates in the cells that form the inner lining of the stomach.
