Effective Ways to Screen for Stomach Cancer

Created by Doctor Peter, 5 months ago

Stomach cancer screening is a critical aspect of healthcare due to its prevalence as the most common gastrointestinal cancer. Globally, hundreds of thousands of new cases are diagnosed each year, making it the second leading cause of cancer-related deaths worldwide. 

Early detection is paramount for favorable treatment outcomes, with the survival rate exceeding 80 to 90% if the disease is identified before invading the muscular layer of the stomach wall.

Effective stomach cancer screening plays a pivotal role in identifying the disease at its earliest stages.

Stomach Cancer Screening: Screening procedures are primarily conducted on individuals who do not exhibit clinical symptoms. In countries where gastric cancer is prevalent, extensive screening programs have proven beneficial in detecting stomach cancer at an early stage. The screening process involves several tests, including gastroscopy, biopsy of suspicious lesions, and tumor marker tests.

Gastroscopy with Narrow Banding Imaging (NBI): To enhance the accuracy of mucosal pathological analysis, gastroscopy with Narrow Banding Imaging (NBI) is employed during stomach cancer screening. This specialized endoscopic technique utilizes a narrow frequency band of light, providing clearer visualization and improved diagnostic capabilities compared to conventional endoscopy.

Diagnostic Tests for Stomach Cancer: In order to confirm the diagnosis and determine the stage of stomach cancer for appropriate treatment planning, a range of tests are performed. These tests aid in the accurate identification of the disease and allow healthcare professionals to provide targeted interventions.

Gastrointestinal Endoscopy: Gastrointestinal endoscopy is a direct visualization technique that allows physicians to examine the targeted area. During the procedure, the doctor may extract a tissue sample (biopsy) from the suspected region to obtain definitive confirmation of the diagnosis. 

Endoscopy is particularly effective in detecting early-stage cancers originating from the upper or lower lining of the digestive tract. Individuals with a high risk of stomach cancer, including those with Helicobacter pylori (HP) infection, inflammatory bowel disease, ulcerative colitis, personal or family history of bowel cancer or other organ cancers, family history of polyps, gastroesophageal reflux disease (GERD), or changes in the lining of the esophagus (Barrett's esophagus), should undergo early and frequent endoscopy screenings.

Biopsy for Stomach Cancer Diagnosis: During an endoscopy, a small tissue sample is obtained from an abnormal area of the stomach for further examination. The collected tissue is analyzed under a microscope to identify the presence of malignant cells, confirming the diagnosis of stomach cancer.

Through effective screening measures such as gastroscopy with NBI, healthcare providers can identify stomach cancer at an early stage, enabling timely interventions and significantly improving treatment outcomes.

Diagnostic tests, including gastrointestinal endoscopy and biopsies, play crucial roles in confirming the diagnosis and staging the disease. By implementing comprehensive screening protocols and leveraging advanced diagnostic techniques, medical professionals can improve the prognosis and overall survival rates for individuals affected by stomach cancer.
