Stomach Cancer - Causes, Prevention, and Treatment

What Is Stomach Cancer?

The growth of cancerous cells within the stomach lining is called stomach cancer or gastric cancer. This cancer is difficult to analyze because it does not cause any symptoms in the earlier stages. Stomach cancer accounts for 1.7 % of new cancer cases worldwide.
