Intraoperative freezing means that the tumor will be sent to the pathology department immediately after the surgery, and the benign and malignant nature of the tumor will be detected within ten minutes after special treatment, and if the tumor is malignant, radical surgery can be performed directly. If the tumor is malignant, radical surgery can be performed directly. In contrast, it takes 3-7 days to get the results of general pathology, and if the tumor is malignant, radical surgery is needed twice; however, the second surgery will not only increase the physical pain and psychological trauma of the patient, but also increase the economic burden of the patient; and the scar adhesion after the first surgery will increase the difficulty of the second surgery, increase the chance of damage to blood vessels and nerves and affect the effect of radical surgery, and also increase the chance of recurrence and metastasis after surgery. It also increases the chance of postoperative recurrence and metastasis. The intraoperative freezing can determine the benignity and malignancy of the tumor intraoperatively, which can cure the malignant tumor at one time and avoid secondary surgery, and also avoid the pain of patients and their families waiting for the result.
