Stomach cancer: 12 signs and symptoms of the silent killer never to be ignored

What to look for: Frequent burning sensation in the upper abdomen or chest, lasting weeks or months.
Direction: If over-the-counter remedies don’t help within 2–3 weeks, see a doctor for evaluation.

What to look for: Losing weight without trying, often alongside decreased appetite.
Direction: Sudden, unintentional weight loss warrants immediate medical consultation.

What to look for: Persistent nausea, occasional vomiting, or vomiting blood (even trace amounts).
Direction: Do not ignore vomiting, especially if accompanied by blood—seek urgent medical attention.

What to look for: Feeling like food is sticking in your throat or chest.
Direction: Requires evaluation with endoscopy or imaging to rule out tumors obstructing the stomach or esophagus.

What to look for: Feeling full after eating very small amounts of food.
Direction: Track your meals and appetite changes, and discuss with a doctor if persistent.

What to look for: Mild to severe pain or bloating in the upper abdomen. Pain may be intermittent or constant.
Direction: Persistent or worsening pain should be investigated with imaging or endoscopy.

What to look for: Black, tarry stools (melena) or vomiting blood (hematemesis).
Direction: Emergency: this is a serious red flag for bleeding in the stomach or gastrointestinal tract.

What to look for: Feeling unusually tired, lethargic, or short of breath with minimal activity.
Direction: Can indicate anemia from chronic bleeding—see a healthcare provider for blood tests.

What to look for: Pale skin, dizziness, or rapid heartbeat.
Direction: Iron-deficiency anemia in adults without obvious cause should prompt evaluation for stomach bleeding or tumors.

What to look for: Chronic abdominal fullness, especially after small meals, accompanied by discomfort.
Direction: Could indicate tumor growth or fluid accumulation; medical assessment needed.

What to look for: Disinterest in food or skipping meals due to discomfort or early satiety.
Direction: Document the duration and severity; long-term loss of appetite needs medical review.

What to look for: Low-grade fever, unexplained chills, or excessive sweating at night.
Direction: May signal systemic effects of cancer; consult a doctor for blood tests and imaging.

Early detection is key—don’t wait if multiple symptoms appear.
Keep a symptom diary—note frequency, duration, and severity of symptoms.
Visit a gastroenterologist—tests like endoscopy, biopsy, and imaging help confirm diagnosis.
Avoid self-diagnosis—many of these symptoms overlap with ulcers, gastritis, or acid reflux.
Follow preventive measures: avoid smoking, limit alcohol, eat a healthy diet rich in fruits and vegetables, and screen if there’s a family history.
