Types of stomach cancer
Every stomach cancer patient is different. The cancer experts at Cancer Treatment Centers of America® (CTCA) have extensive experience in properly staging and diagnosing the disease, and developing a treatment plan that's tailored to your specific type of stomach cancer.
Different types of stomach cancer include:
- Adenocarcinomas develop within the cells of the innermost lining of the stomach. The majority of stomach cancers are classified as adenocarcinomas.
- Lymphoma is a cancer of the immune system tissue that may start anywhere there are lymph tissues, including the stomach. Lymphomas in the stomach are rather rare and only account for about 4 percent of all stomach cancers.
- Gastrointestinal stromal tumors, or GISTs, are a rare type of stomach cancer that starts in a special cell found in the lining of the stomach called interstitial cells of Cajal (ICCs). Under a microscope, GIST cells look similar to muscle or nerve cells. These tumors may develop throughout the digestive tract, but about 60 to 70 percent occur in the stomach.
- Carcinoid tumors typically start in the hormone producing cells of the stomach. These tumors usually do not spread to different organs and account for only about 3 percent of stomach cancer incidence.
