Stomach Cancer Symptoms

For some people with stomach cancer, symptoms may begin with things such as indigestion, feeling bloated after eating, loss of appetite, and heartburn; however, not everyone with the disease will experience early symptoms of stomach cancer. As the disease progresses, stomach cancer symptoms may include blood in the stool, stomach pain, unexplained weight loss, and jaundice.

 

Stomach Cancer Symptoms: An Introduction

Stomach cancer usually develops over time. As stomach cancer cells continue to grow, they spread more deeply into the stomach and to surrounding areas. When stomach cancer spreads (metastasizes) outside of the stomach, it tends to spread to nearby lymph nodes, the liver, the lungs, and other organs. When this occurs, the new tumor has the same kind of abnormal cells as the primary tumor in the stomach.
 
This eMedTV article uses the term "stomach cancer" to refer to gastric adenocarcinoma (cancer of the glandular tissue in the stomach). This is the most common type of stomach cancer. Other types of stomach cancer include lymphomas (cancers involving the lymphatic system) and sarcomas (cancers of the connective tissue, such as muscle, fat, or blood vessels).

Early Stomach Cancer Symptoms

Not everyone with the disease will experience early stomach cancer symptoms. When early symptoms of stomach cancer do appear, they tend to be vague or minor and may include such things as:
 
  • Indigestion and stomach discomfort
  • A bloated feeling after eating
  • Mild nausea
  • Loss of appetite
  • Heartburn.
 
Pain is not normally an early symptom of stomach cancer; don't wait to feel pain before seeing a doctor.
