Early stomach cancer often does not cause symptoms. As the cancer grows, the most common symptoms are:

• Discomfort or pain in the stomach area
• Difficulty swallowing
• Nausea and vomiting
• Weight loss
• Feeling full or bloated after a small meal
• Vomiting blood or having blood in the stool

Most often, these symptoms are not due to cancer. Other health problems, such as an ulcer or infection, can cause the same symptoms. Anyone who has these symptoms should tell their doctor so that problems can be diagnosed and treated as early as possible.
