Will Needle Biopsy Cause Lymph Node Metastasis?

Pathological diagnosis is through the complete excision of the tumor or a part of the tumor tissue, after many steps of treatment, the pathologist observes the morphology and other internal characteristics of the tissue cells through a microscope, and analyzes and judges the final diagnosis of the tumor, which is the diagnosis of all malignant tumors. the gold standard. Superficial lymph nodes can be directly excised and biopsied, while deep lesions need to be guided by B-ultrasound or CT-guided needle biopsy. Gastrointestinal, nasopharyngeal, and respiratory lesions can undergo endoscopy and biopsy, and thoracic, pelvic, and abdominal lesions can undergo thoracic, laparoscopy, and biopsy. If necessary, laparotomy and thoracotomy may be required to obtain pathological tissue. So will lymphoma cancer metastasize through the membrane damaged by puncture? In theory, this situation exists, but patients may wish to weigh the pros and cons. If it is a malignant tumor, even if it is not punctured, as the disease progresses, tumor cells will break through the membrane and invade nearby or even distant places. Another characteristic of malignant tumors is that they can spread widely with blood and lymph, which is not controlled by the capsule at all.
