Detecting Colorectal Cancer Early: A Comprehensive Guide to Screening Methods in Vietnam

In Vietnam, colorectal cancer is becoming increasingly common, with a growing number of cases being reported each year. Fortunately, there are several screening methods available to detect this form of cancer early on, including stool tests.

Stool tests are non-invasive and can be used to identify the presence of colorectal cancer or precancerous polyps in stool samples. 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 a symptom of colorectal cancer. The FIT uses antibodies to detect blood in small stool samples collected at home. Stool DNA testing looks for abnormal DNA fragments released from cancer cells or polyps in the stool sample, which can 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, as it allows 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 crucial to improving the prognosis and quality of life for colorectal cancer patients. Risk factors for this form of 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 from developing further.
