Ovarian Cancer Diagnosis

Ovarian cancer is a malignant tumor with insidious early symptoms. Without timely diagnosis and treatment, the tumor may progress rapidly and spread, severely impacting patient survival rates. Effective examination and diagnosis are essential for treatment planning and prognosis evaluation. Common diagnostic methods include imaging, tumor marker testing, and histopathological biopsy.

Diagnostic Basis

1. Imaging Examination
Ultrasound is the primary method for initial screening, allowing assessment of ovarian size and morphological abnormalities. CT and MRI help determine the extent of tumor spread and lymph node involvement, guiding surgical planning.

2. Tumor Marker Testing
Serum CA-125 is a commonly used tumor marker for ovarian cancer. Elevated levels suggest malignancy, though specificity is limited. Combined detection with novel markers such as HE4 helps improve diagnostic accuracy.

3. Histopathological Diagnosis
Biopsy obtained via laparoscopy or surgery for pathological analysis is the gold standard for confirming ovarian cancer. Pathological classification and staging provide guidance for subsequent treatment.

4. Molecular and Immunological Testing
Molecular testing helps identify tumor gene mutations to guide targeted therapy. Immune reconstruction cell therapy not only serves as a treatment but also assists in monitoring efficacy after diagnosis for some patients.

5. Auxiliary Diagnostic Techniques
PET-CT combines metabolic information to distinguish between benign and malignant tumors and detect metastasis, enhancing diagnostic comprehensiveness.

Conclusion

Ovarian cancer diagnosis requires multidisciplinary collaboration, relying on imaging, tumor marker testing, and pathology. Experts at United Life International Medical Center stress that standardized diagnostic processes and the application of new technologies contribute to early detection and precise treatment, significantly improving patient quality of life.
