Gastric cancer – Causes, symptoms, and management
Gastric or stomach cancer can develop in any part of the stomach. In most cases, it occurs in the central part of the stomach, known as the stomach body. In other cases, the cancer develops in the gastroesophageal junction, where the esophagus and stomach are connected. In both cases, cancer cells grow abnormally in the stomach regions. Here are some common causes, symptoms, and management options for gastric or stomach cancer. Causes Stomach cancer develops due to genetic mutation or changes in the DNA present in the cells of the stomach. As a result of this mutation, the cells begin to grow faster, causing a tumor to form over time. With the cancer progressing, the number of cancer cells outgrows the number of healthy cells. As time passes, the cancerous cells in the stomach can progressively invade and harm healthy tissues. The cells penetrate deeper into the stomach and eventually break away from the abdominal area to spread to other body parts during the advanced stages. If cancerous cells migrate to another part of the body, it is known as metastasis. Researchers have yet to learn why the mutation occurs. However, conclusive studies indicate that certain factors increase the risk of gastric cancer.
