Stomach Cancer Symptoms

Stomach Cancer Symptoms

The symptoms of stomach cancer are in two distinct stages:

  • Early stage stomach cancer symptoms
  • Advanced stomach cancer symptoms

Early Stage Stomach Cancer Symptoms

It is common for people with early stage stomach cancer to experience no symptoms. However, as stomach cancer grows and spreads, it exhibits some telltale signs and symptoms, even while still in the early stages.

Symptoms may include:

  • Unexplained weight loss
  • Abdominal pain or vague pain just above the belly button area
  • Indigestion, heartburn or vomiting
  • Loss of or decrease in appetite
  • Weakness or fatigue
  • Blood in vomit or stool
  • A feeling of fullness after small meals

Many symptoms of early stage stomach cancer are also the symptoms of less serious stomach issues. If you are experiencing any of these signs and symptoms, it is important to see your doctor. The earlier we diagnose the cancer, the more successfully we can treat it.

Advanced Stomach Cancer Symptoms

Symptoms of advanced stomach cancer are more serious than symptoms of early stage stomach cancer. Because advanced stage stomach cancer has grown and spread, it can also effect nearby organs including:

  • The liver
  • The large intestine (also known as the colon)

If stomach cancer has grown to create a blockage within the stomach or the large intestine, you may experience:

  • Loss of appetite
  • Significant weight loss
  • Uncontrolled vomiting
Signs that stomach cancer has spread to the liver include:
  • Jaundice (yellowing of skin or eyes)
  • Ascites (enlargement of stomach from fluid)
