Stomach cancer symptoms

Most patients with early stage stomach cancers have no symptoms of the disease. In other cases, a person with stomach cancer may mistake their symptoms for a common stomach virus.

When the signs and symptoms of stomach cancer are not apparent, the disease may reach advanced stages before a diagnosis is made. For this reason, it is important for anyone considered to be at high risk to talk to their doctors about symptoms that may be signs of stomach cancer.

Stomach cancer symptoms

Some common stomach cancer symptoms may include:

  • Unexplained weight loss: Lack of appetite or unexplained weight loss is a common sign of cancer.
  • Stomach pain: Abdominal discomfort or pain in the abdomen above the navel could be a symptom of stomach cancer. Also, swelling or fluid build-up in the abdomen may also be caused by stomach cancer.
  • Feeling full: Many stomach cancer patients experience a sense of "fullness" in the upper abdomen after eating small meals.
  • Heartburn: Indigestion, heartburn or symptoms similar to an ulcer may be signs of stomach cancer.
  • Nausea & vomiting: Some stomach cancer patients have symptoms that include nausea and throwing up. Sometimes the vomit may have blood in it.

Understanding cancer symptoms

These symptoms may be attributed to a number of conditions other than cancer. If you notice any cancer signs or symptoms, it's important to visit your doctor for an accurate diagnosis.
