What is gastric cancer surgery?
The build-up of abnormal cells in the lining of the stomach causes stomach cancer, also known as gastric cancer. Smoking, alcohol consumption, unhealthy diet, and obesity are certain lifestyle aspects that can increase the risk of cancer.
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.
