What is the Difference Between Gastritis and Stomach Cancer?

Gastritis and stomach cancer are two distinct medical conditions that affect the stomach. The main differences between them are:

Definition: Gastritis is the inflammation of the lining of the stomach, while stomach cancer is the abnormal growth of cells that starts in the stomach.
Cause: Gastritis is caused by weakness or injury in the mucus-lined barrier that protects the stomach wall, while stomach cancer is caused by changes in the DNA of the stomach cells.
Symptoms: Although both conditions may present with similar symptoms, stomach cancer often goes undetected in the early stages due to the lack of warning signs. Common signs of stomach cancer include nausea, vomiting, change in appetite, swelling of the abdomen, heartburn, indigestion, abdominal pain or discomfort, and upper abdomen fullness after consuming a small amount of food. In contrast, gastritis typically causes symptoms such as swelling and irritation of the inside of the stomach.
Types: Stomach cancer can be classified into different types, such as adenocarcinoma (the most common type), lymphoma, and gastrointestinal stromal tumors (GIST). Gastritis does not have specific types.
Progression: Gastritis is a non-cancerous condition that can be managed with medication or lifestyle changes. Stomach cancer, on the other hand, is a progressive and potentially life-threatening disease that may require more extensive medical intervention.

It is essential to consult a doctor for proper diagnosis and treatment if experiencing symptoms suggesting either gastritis or stomach cancer. Early detection and treatment can significantly improve the prognosis for both conditions.
