Stomach cancer, or gastric cancer, begins when healthy cells in the stomach become abnormal and «grow out of control.»
The ASCO adds: “Most stomach cancers are a type called adenocarcinoma.
“This means that the cancer started in the glandular tissue that lines the inside of the stomach.
«Other types of cancerous tumors that form in the stomach include lymphoma, gastric sarcoma, and neuroendocrine tumors, but these are rare.»
