What is stomach cancer?
Stomach cancer, also known as gastric cancer, occurs when normal healthy cells are replaced by cancerous cells within the lining of the stomach. The stomach is located below the esophagus and is the tube through which food passes into the intestines after swallowing. The stomach is the part of the digestive tract that digests food and moves nutrients through the intestines to the small intestine.
This type of cancer is usually slow growing and takes years to develop. Stomach cancer occurs when normally healthy cells begin to grow out of control in the lining of the stomach. This collection of cancer cells is called a tumor, and over time, these cells spread to other layers of the stomach.
