What are the types of gastric cancer?
Depending on where cancer occurs, it can be of the following types:
Adenocarcinoma: It forms in the mucosa or the innermost lining of the stomach. It is the most frequent type of stomach cancer and accounts for 90-95% of them.
Lymphoma: It is an immune system tissue cancer that occurs rarely in the stomach. Its treatment will depend on its type.
Gastrointestinal stromal tumor (GIST): This is a rare tumor which forms in a special cell called interstitial cells of Cajal (ICC). While it can occur anywhere in the digestive tract, it is more common in the stomach.
Carcinoid tumor: It occurs in the hormone-making stomach cells. It is rare and does not generally spread to other organs.
