The symptoms of stomach cancer vary from person to person. Cancer in early stages may have mild or no symptoms. The symptoms may also be like those of other diseases or conditions.
The most common symptoms of stomach cancer include:
Indigestion or heartburn
Feeling like food gets stuck in your throat when eating
Feeling of fullness or bloating after eating even small amounts of food
Nausea and vomiting (this often happens soon after eating)
Diarrhea or constipation
Blood in your stool
Loss of appetite
Unexplained weight loss
Weakness and tiredness
Stomach cancer that’s more advanced can block your stomach or intestines. This can cause vomiting that doesn’t go away. Stomach cancer can also spread to your liver. If this happens, it can cause yellowing of your skin and the white part of your eyes (jaundice). Or it can cause fluid buildup in your belly (ascites).
Many of these symptoms may be caused by other health problems. So it's important to see your healthcare provider if you have these symptoms. Your healthcare provider will examine you and order tests to find out if you have stomach cancer.
