Description

What exactly is this screening test?

Gastric (Stomach) Cancer Screening involves tests and evaluations to detect early signs of stomach cancer. Common screening methods include upper endoscopy, where a thin, flexible tube with a camera (endoscope) is inserted through the mouth to examine the stomach lining, and imaging tests like barium swallow X-rays. Biopsy samples may also be taken during endoscopy to check for cancerous cells.

Health Importance

Why is this test crucial for your health?

Early detection of gastric cancer is crucial because it significantly improves treatment outcomes and survival rates. Gastric cancer often presents with non-specific symptoms, making early detection challenging. Screening helps identify cancer at an early stage when it is more likely to be treatable and curable, preventing the spread to other parts of the body.

Target Audience

Who should consult their doctor about this test?

• Individuals with persistent symptoms: Such as unexplained weight loss, persistent stomach pain, nausea, vomiting, difficulty swallowing, or feeling full quickly.
• People with a family history: Of gastric cancer or genetic conditions that increase the risk of stomach cancer.
• Individuals with risk factors: Such as Helicobacter pylori infection, chronic gastritis, smoking, or high salt and smoked food diet.
• Older adults: Especially those over 50, as the risk of gastric cancer increases with age.
• Individuals with certain genetic syndromes: Such as Lynch syndrome or familial adenomatous polyposis (FAP), which increase the risk of gastric cancer.

Procedure

How is the test conducted?

• Preparation: You may need to fast for several hours before the procedure. Follow any specific instructions provided by your healthcare provider.
• During the test:
  • Upper endoscopy: You will be given a sedative to help you relax. A thin, flexible tube with a camera (endoscope) is inserted through your mouth and down into your stomach to examine the lining and take biopsy samples if necessary.
  • Barium swallow X-rays: You will drink a barium solution that coats the lining of your stomach, making it visible on X-rays. Multiple X-rays are taken to look for abnormalities.
• After the test: You may need to rest until the sedative wears off. Your healthcare provider will review the results with you and discuss any necessary follow-up or treatment if abnormalities are detected.

Benefits

What are the primary benefits of undergoing this screening?

• Early detection: Identifies gastric cancer at an early stage, improving treatment outcomes and survival rates.
• Preventive care: Allows for the monitoring of at-risk individuals and early intervention if abnormalities are detected.
• Peace of mind: Provides reassurance by confirming the absence of cancer or addressing concerns promptly.
• Guided treatment: Helps healthcare providers develop effective treatment plans based on accurate diagnosis.
• Improved prognosis: Early treatment can significantly improve survival rates and reduce the need for more aggressive treatments.

Risks and Limitations

Are there any potential risks or limitations?

• Risks: The procedures are generally safe but may involve slight discomfort, cramping, or a sore throat. Rarely, there can be more serious complications such as infection, bleeding, or perforation of the stomach.
• Limitations: No screening test is 100% accurate. False positives and false negatives can occur, and further testing may be required to confirm a diagnosis. Not all cases of gastric cancer are detected early, especially if the cancer is in its very early stages or in a location difficult to reach with endoscopy.

Frequency

How often should this screening be done?

• Individuals with persistent symptoms: Should seek evaluation as soon as symptoms are noticed.
• People with risk factors: Regular screening as recommended by their healthcare provider.
• Routine check-ups: Older adults or those with a family history of gastric cancer should discuss the need for screening during routine check-ups.
