gastric stomach cancer
Stomach cancer begins when cancer cells form in the inner lining of your stomach. These cells can grow into a tumor. Also called gastric stomach cancer, the disease usually grows slowly over many years.If you know the symptoms it causes, you and your doctor may be able to spot it early, when it’s easiest to treat.
What Causes Gastric Stomach Cancer?
Scientists don’t know exactly what makes cancer cells start growing in the stomach. But they do know a few things that can raise your risk for the disease. One of them is infection with a common bacteria, H. pylori, which causes ulcers. Inflammation in your gut called gastritis, a certain type of long-lasting anemia called pernicious anemia, and growths in your stomach called polyps also can make you more likely to get cancer.
Other things that seem to play a role in raising the risk include:
- Being overweight or obese
- A diet high in smoked, pickled, or salty foods
- Stomach surgery for an ulcer
- Type-A blood
- Epstein-Barr virus infection
- Certain genes
- Working in coal, metal, timber, or rubber industries
- Exposure to asbestos
Symptoms of gastric stomach cancer include indigestion and stomach discomfort or pain.
These and other signs and symptoms may be caused by gastric stomach cancer or by other conditions.
