Blood Tests Alone Insufficient for Early Colorectal Cancer Detection
While blood tests are becoming more accessible for colorectal cancer screening [[3]],experts emphasize they should not be the only method used for early detection.
The Limitations of Blood Analysis
It is a common misconception that a simple blood test can detect all diseases. Though, when it comes to colorectal cancer, relying solely on blood analysis can be a mistake. Blood tests do not allow the early detection of colorectal cancer,
according to Pham Cam Phuong, director of the Center for Nuclear Medicine and Oncology at Bach mai Hospital.
Did You Know?
Colorectal cancer, when detected early, has a high treatment success rate, with a 5-year survival rate possibly reaching 90%.
Signs of colorectal cancer frequently enough become apparent only when the disease has progressed to an advanced stage. therefore, a comprehensive approach is necessary for effective screening.
Recommended Screening Methods
The primary methods for early detection of colorectal cancer include:
- Colonoscopy: A visual examination of the colon using a flexible tube with a camera.
- Fecal occult Blood Test (FOBT): A test to detect hidden blood in the stool.
- Tissue Biopsy: Examination of suspicious tissue samples.
These methods allow for the identification of polyps or early-stage cancer, significantly improving the chances of triumphant treatment.
Pro Tip
Individuals aged 45 and older should undergo regular colorectal cancer screening, as recommended by healthcare professionals [[1]].
Personalized Treatment Approaches
Early detection is crucial because colorectal cancer is completely curable if detected in time.
When patients experience symptoms such as digestive disorders, abdominal pain, changes in stool, blood in the stool, or a constant urge to use the bathroom, they should seek medical attention promptly.
Dr. Phuong advises:
But wait for symptoms to appear before consulting with a doctor. It is necessary to perform periodic and proactive detection tests with high precision methods such as colonoscopy, especially after 45 years, to detect polyps or cancer early, when the healing rate can reach 90%.

Prioritizing proven and internationally standardized tests, such as in vitro diagnostics, ensures accuracy and reliability, enabling doctors to tailor the most appropriate treatment plan for each patient.
The Role of Genetic Testing
Genetic tests play a vital role in determining the most effective drugs or immunotherapies during the treatment phase. This personalized approach aims to match the appropriate drug, the appropriate patient, at the right time.
However, the cost of genetic testing can be a barrier for some patients.
