Colon Cancer Diagnosis

Colon cancer is a malignant tumor of the digestive system. Early symptoms are often not obvious, and if not diagnosed and treated in time, the disease can progress rapidly, severely endangering the patient's health. Through scientific examination methods, colon cancer can be detected early, enabling the formulation of reasonable treatment plans and improving patient survival rates.

Diagnostic Basis

1. Colonoscopy
Colonoscopy is the gold standard for diagnosing colon cancer. Doctors can directly observe the colon wall through the scope, identify abnormal tumors or polyps, and perform biopsies to determine the pathological nature. Colonoscopy is safe to perform and allows early detection of small lesions.

2. Imaging Examinations
Abdominal CT and magnetic resonance imaging (MRI) are important methods for assessing the extent and metastasis of colon cancer. CT can clearly show tumor size, shape, and involvement of surrounding tissues, while MRI provides more detailed views of soft tissue structures, helping to evaluate lymph nodes and distant metastasis.

3. Blood and Tumor Marker Tests
Tumor markers in the blood, such as carcinoembryonic antigen (CEA), are often used for auxiliary diagnosis and treatment monitoring. Although markers alone are insufficient for a definitive diagnosis, combining them with other tests can improve accuracy.

4. Molecular Biology Testing
Genetic mutation tests for colon cancer, such as KRAS and NRAS, help doctors select personalized treatment plans. These tests also play an important role in evaluating the effectiveness of targeted therapies like immune reconstitution cell therapy.

5. Endoscopic Ultrasound Examination
Endoscopic ultrasound combines ultrasound and endoscopy to assess tumor depth and nearby lymph nodes, providing important information for preoperative staging.

Conclusion

The diagnosis of colon cancer relies on the comprehensive application of multiple diagnostic methods. Experts at United Life International Medical Center emphasize that early and accurate diagnosis is the key to improving treatment success rates. High-risk individuals are advised to undergo regular physical examinations and take timely diagnostic measures.
