Signs and Symptoms of Stomach Cancer You Should Watch For
This article highlights key symptoms and signs of stomach cancer, emphasizing the importance of early detection for effective treatment. It discusses common early and late symptoms, diagnostic methods like endoscopy, and the significance of prompt medical attention to improve outcomes.

Detecting stomach cancer in its early stages is challenging because initial signs are often mistaken for minor ailments. Many overlook symptoms, attributing them to stomach ulcers or infections. Usually, individuals over 40 are more prone, but those above 55 experiencing ongoing issues should consult a healthcare professional promptly. Although Western countries see a decline, stomach cancer remains a leading cause of cancer mortality worldwide, ranking third overall. Early diagnosis is crucial for successful treatment, which may include surgery and chemotherapy depending on the stage and patient health.
Common early symptoms include:
Persistent fatigue and weakness
Nausea and discomfort
Heartburn and indigestion
Frequent burping
Feeling full after small meals
Bloating after eating
Difficult swallowing
Upper abdominal pain
Low iron causing anemia
Unexplained weight loss
Early detection occurs in only about 20% of cases. Most symptoms appear later, indicating advanced disease. Symptoms of late-stage stomach cancer include vomiting blood, stomach pain, and black stools, which suggest internal bleeding. Diagnosis often involves upper endoscopy, where a doctor visualizes the stomach lining. Abnormal tissue is biopsied to confirm if cancerous, guiding treatment options tailored to the patient’s health and cancer stage.
