Cancer screening in gastroenterology involves various tests and procedures to detect cancer or precancerous conditions in the digestive system at an early stage.
Purpose of the Procedure
The main goal is to detect cancer early when it's most treatable, or to prevent cancer by identifying and removing precancerous lesions.
Common Screening Procedures
- Colonoscopy for colorectal cancer
- Upper endoscopy for esophageal and stomach cancer
- Fecal occult blood test for colorectal cancer
- CT colonography (virtual colonoscopy)
Note: The type and frequency of screening depend on individual risk factors and age.
Benefits
- Early detection of cancer when treatment is most effective
- Prevention of cancer through removal of precancerous lesions
- Reduced cancer mortality rates
- Peace of mind for patients at risk
