Symptoms
Unfortunately, stomach cancer rarely causes symptoms in its early stages, making this disease often advanced when detected. Also, any symptoms that may appear are relatively common, they are non-specific and can easily be mistaken for less serious conditions. Stomach cancer often reaches an advanced stage or even may spread to other sites before diagnosis. The signs and symptoms of early stage stomach cancer may include:
Heartburn and indigestion
Unexplained upper abdomen discomfort
New onset of feeling bloated or unusually full after eating
Poor appetite
Nausea
Once the disease has progressed to a more advanced stage, patients may experience the following symptoms:
Unintentional weight loss
Black or bloody stools
Vomiting or vomiting blood
Swelling in the abdomen
Pain in the upper abdomen
Anemia, weakness, or fatigue
