People with stomach cancer may experience the following symptoms: Symptoms are changes you feel in your body.

Abdominal pain and discomfort
Nausea and vomiting, especially soon after eating solid food
Diarrhea or constipation
Bloating after eating

If you’re concerned about any changes you’re experiencing, talk to your doctor. Your doctor will ask, among other questions, how long and how often you have been experiencing symptoms. This is called a diagnosis to help find the cause of the problem.
If cancer is diagnosed, symptom relief remains an important part of cancer care and treatment. It usually begins soon after diagnosis and continues throughout treatment. Symptom management may be called “palliative care” or “supportive care.” Be sure to talk to your health care team about any symptoms you’re experiencing, including new symptoms or changes in symptoms.
