Is Biopsy Always Necessary?
Based on patients’ age, symptoms, clinical findings supported by CT/MRI/PET scans an oncologist can diagnose the presence of cancer with reasonable certainty. However, the gold standard for diagnosing a cancer is considered to be a biopsy. Hence ,to start a cancer directed treatment a diagnosis based on biopsy is required.
A biopsy is not mandatory for surgical treatment of cancers arising in certain areas. This is considering the procedural complexity to obtain a biopsy from such areas , risks of complications , risk of tumor spillage, risk of false negative results. In such scenarios, usually, other noninvasive diagnostic modalities like CT/MRI/PET scans have very good diagnostic yield.
