In Vietnam, colorectal cancer has become a growing concern, with an increasing number of cases being reported each year. Several screening methods are available to detect colorectal cancer, including stool tests. Stool tests are non-invasive ways to 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 a symptom 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, 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. This procedure 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 for 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 that you may have colorectal cancer or would like more information about screening options and treatment plans, it is important to speak with your doctor as soon as possible. Timely diagnosis and treatment can greatly improve your chances of survival and quality of life following a diagnosis of colorectal cancer.
