Full Answer

There is more than one type of stomach cancer, according to Mayo Clinic. Cancer that begins in glandular cells is called an adenocarcinoma, while cancer that begins in immune system cells is referred to as lymphoma. Cancer that begins in cells that produce hormones is called a carcinoid tumor, and cancer that begins in nervous system tissue is a gastrointestinal stromal tumor. Most stomach tumors that are cancerous are adenocarcinomas. Carcinoid, lymphoma and gastrointestinal stromal tumors are rare types of stomach cancers.
