Most cancers of the stomach (about 90% to 95%) are adenocarcinomas. These cancers develop from the gland cells in the innermost lining of the stomach (the mucosa).
If you are told you have (or gastric cancer), it will almost always be an adenocarcinoma.
There are 2 main types of stomach adenocarcinomas:
š¹The intestinal type tends to have a slightly better prognosis (outlook). The cancer cells are more likely to have certain gene changes that might allow for treatment with targeted drug therapy.
š¹The diffuse type tends to grow spread more quickly. It is less common than the intestinal type, and it tends to be harder to treat.
Other types of that can start in the stomach include gastrointestinal stromal tumors (GISTs), neuroendocrine tumors and lymphomas.
