Stomach cancer may not cause symptoms in its early stages. This means that it is usually diagnosed when the cancer is more advanced.
Common symptoms are listed below. These symptoms can also occur in many other conditions and do not necessarily mean that you have cancer. Speak with your general practitioner (GP) if you are concerned.

- persistent nausea and/or vomiting with no apparent cause
