In Vietnam, colorectal cancer is a growing concern as cases continue to rise. Several methods are available for detecting colorectal cancer, including stool tests. Stool tests are non-invasive and can identify the presence of colorectal cancer or precancerous polyps in a patient’s stool sample. There are three types of stool tests: fecal occult blood test (FOBT), fecal immunochemical test (FIT), and fecal DNA test.
The FOBT detects hidden blood in a patient’s stool sample, which can be an early sign of colorectal cancer. The FIT uses antibodies to detect blood in a small stool sample collected at home. Stool DNA testing looks for abnormal DNA fragments released from cancer cells or polyps in the stool sample. These tests help determine if a patient has cancer or is at risk of developing it.
Colonoscopy is considered the “gold standard” for screening and diagnosing colorectal cancer, allowing doctors to examine the entire colon and rectum for early signs of cancer or precancerous lesions. Advanced endoscopic methods like submucosal dissection (ESD) and submucosal resection (EMR) can effectively treat early-stage colorectal cancer without the need for additional support.
Early detection, appropriate treatment, and regular follow-up care are essential to improving the prognosis and quality of life for colorectal cancer patients. Risk factors for colorectal cancer include obesity, red meat consumption, smoking, alcohol abuse, and lack of physical activity. Endoscopy can help detect and remove polyps to prevent colorectal cancer.
If you suspect you may have colorectal cancer or need guidance on screening options, it is crucial to consult with a healthcare professional who can develop an early treatment plan that includes regular follow-up care. Timely diagnosis and treatment are critical for improving survival rates and quality of life among colorectal cancer patients in Vietnam.
