Stomach Cancer

gastric cancer (stomach cancer)

Stomach or gastric cancer is a disease in which cancer cells form in the lining of the stomach. The wall of the stomach is made up of three layers of tissue: the mucosal layer, the muscularis layer, and the serosal layer. Stomach cancer begins in the cells lining the mucosal layer and spreads through the outer layers as it grows.

Stromal tumors of the stomach begin in supporting connective tissue and are treated differently from gastric cancer.

An estimated 26,380 new cases of stomach cancer will be diagnosed in the United States and 11,090 people are expected to die from stomach cancer in 2022, according to the National Cancer Institute’s Surveillance, Epidemiology, and End Results (SEER) Program. Age, diet, and stomach disease can affect the risk of developing gastric cancer.
