Research is increasing regarding what we know about Gastric Cancer. Scientists are learning more about its causes. Following are common risk factors for the disease:
- Patients who have parents, brothers, sisters, or children with a history of stomach cancer are somewhat more likely to develop the disease themselves.
Helicobacter Pylori Infection
- H. pylori is a bacterium that commonly infects the inner lining (the mucosa) of the stomach. Infection with H. pylori can cause stomach inflammation and peptic ulcers.
Long Term Inflammation of the Stomach
- People who have conditions associated with long-term stomach inflammation (such as the blood disease pernicious anemia) are at increased risk of stomach cancer.
- Studies suggest that people who eat a diet high in foods that are smoked, salted, or pickled have an increased risk for stomach cancer. Also, patients who are obese and lack physical activity may increase the risk of stomach cancer.
- Smokers are more likely than nonsmokers to develop Stomach Cancer.
Signs and Symptoms
Early stomach cancer often does not cause symptoms. As the cancer grows, the most common symptoms are:
- Difficulty swallowing
- Discomfort or pain in the stomach area
- Feeling full or bloated after a small meal
- Nausea and vomiting
- Vomiting blood or having blood in the stool
- Weight loss
