Most stomach cancer is caused by Helicobacter pylori infection. Diet foods are not proven causes, but some foods, such as smoked foods, salted fish and meat, and pickled vegetables are associated with a higher risk.
Types of Stomach CancerEdit
There are several types of stomach cancer, which can be categorized based on the location in the stomach where the cancer begins. The most common type of stomach cancer is adenocarcinoma, which starts in the cells lining the inside of the stomach. Other types of stomach cancer include:
- Lymphoma: This type of cancer starts in the lymphatic system, which is a network of vessels and nodes that help circulate blood and fight infection.
- Sarcoma: This type of cancer develops in the connective tissues or muscles of the stomach.
- Gastrointestinal stromal tumor (GIST): This type of tumor arises from the interstitial cells of Cajal, which are specialized cells that control the movement of food through the digestive tract.
- Carcinoid tumor: This type of tumor arises from the neuroendocrine cells in the stomach, which produce hormones that regulate digestion.
