Significance Of Biopsy Needle:

Some doctors rush to perform partial resection or curetting of a tumor without a preoperative biopsy, only to discover that it is a malignant tumor afterward -- resulting in a minor operation that should have been major, causing the tumor cells to spread beyond control. Similarly, some physicians think it is a malignant spinal tumor, and do large, high risk surgery, the result of postoperative pathology confirmed that no surgery, or only minor surgery. The above situation is not rare in clinical practice -- misdiagnosis and mistreatment simply based on clinical experience will seriously affect the prognosis and quality of life of patients, and bring new hazards.
