Risk of tumor puncture

Cytological examination or pathological examination of tumor puncture is one of the most common means to diagnose malignant tumor or distinguish benign and malignant tumor. If tumor puncture is a tumor on the body surface, it can show bleeding, infection and pain at the puncture site; if anesthesia is used for tumor puncture on the body surface, it may show adverse reactions such as anaphylactic shock; If the space-occupying lesions punctured into the internal organs are generally punctured under CT or B-ultrasound, they will still show pain, hemorrhage and infection at the puncture site; for example, lung puncture can show pneumothorax, hemothorax, etc., and if they are mistakenly penetrated into adjacent organs or tissues, corresponding damage can be caused.
