Stomach Cancer Symptoms: Key Signs and Diagnostic Options - Gastroenterology and Hepatology

Understanding stomach cancer symptoms and diagnostic options is crucial for early detection and treatment. Stomach cancer, or gastric cancer, often presents with vague symptoms, especially in its early stages, which can make it challenging to diagnose. Here’s a comprehensive overview based on your questions.


1. Intermittent Stomach Pain and Stomach Cancer
Stomach cancer can indeed cause intermittent pain. Patients may experience episodes of discomfort or pain that can vary in intensity and frequency. This variability can be attributed to several factors, including the tumor's location, size, and whether it is causing any obstruction or irritation in the stomach lining. However, it is important to note that not all stomach pain is indicative of cancer. Conditions such as gastritis, peptic ulcers, or functional dyspepsia can also cause similar symptoms.


2. Symptoms Associated with Stomach Cancer
While stomach cancer can be asymptomatic in its early stages, certain symptoms may raise suspicion. These include:
- Persistent stomach pain: Especially if it is severe or unusual.

- Nausea and vomiting: Particularly if there is blood in the vomit.

- Loss of appetite: A significant decrease in appetite or feeling full after eating small amounts.

- Unexplained weight loss: Losing weight without trying can be a red flag.

- Difficulty swallowing: This may occur if the tumor is located near the esophagus.

- Bloating or a feeling of fullness: This can be particularly noticeable after meals.

- Fatigue: General tiredness or weakness can be a sign of anemia, which may occur with stomach cancer.

- Black or tarry stools: This can indicate bleeding in the gastrointestinal tract.

If your mother is experiencing stomach pain at night, it may be worth discussing these symptoms with her healthcare provider, as they could indicate a more serious underlying issue.


3. Diagnostic Options for Stomach Cancer
The most definitive method for diagnosing stomach cancer is through an upper gastrointestinal (GI) endoscopy, commonly known as a gastroscopy. During this procedure, a thin, flexible tube with a camera is inserted through the mouth to visualize the stomach lining and take biopsies of any suspicious areas.
In addition to endoscopy, other diagnostic methods include:
- Imaging Studies:
- CT Scan: A computed tomography scan can help visualize the stomach and surrounding organs, providing information about the tumor's size and whether it has spread.

- MRI: Magnetic resonance imaging may also be used in certain cases to assess the extent of the disease.

- Ultrasound: While not as definitive for stomach cancer, abdominal ultrasound can help assess other abdominal organs and detect fluid accumulation.

- Blood Tests: While no specific blood test can definitively diagnose stomach cancer, certain markers like CA 72-4 may be elevated in some patients. However, these tests lack specificity and should not be used alone for diagnosis.

- Endoscopic Ultrasound (EUS): This is a specialized form of endoscopy that uses ultrasound to obtain images of the stomach wall and surrounding tissues, helping to assess the depth of tumor invasion and lymph node involvement.


Conclusion
If your mother is experiencing persistent or worsening symptoms, it is essential to consult with a healthcare professional who can recommend appropriate diagnostic tests. Early detection of stomach cancer significantly improves treatment outcomes, so addressing any concerning symptoms promptly is crucial. Encourage her to maintain open communication with her healthcare provider about her symptoms and any changes she experiences.
