Excuse me, what is the risk of soft tissue tumor incision biopsy?

Biopsy is necessary for accurate diagnosis to determine prognosis and treatment options. Malignant tumors can be staged. If possible, sarcomas can be histologically classified. The design of the sarcoma treatment plan should take into account the characteristics of local growth, the probability of metastasis and the most likely site of distant spread. It is important to obtain adequate specimens from the appropriate site of the sarcoma for accurate diagnosis and staging. Tumors in the extremities are usually cut longitudinally The tumor can be completely excised at the time of biopsy. The most ideal excisional biopsy for most acral tumors is to remove a small amount of adjacent tissue at the same time. For tumors larger than 2 cm in diameter, partial excisional biopsy should be avoided because this method may cause tumor growth. Contamination of surrounding tissue may result in increased final resection. Deep tumors can be diagnosed with central tumor biopsy, but limited specimens may make tumor grading and prognosis difficult. Fine-needle aspiration (FNA) cytology is best diagnosed in cases A large number of units and multidisciplinary cooperation are carried out because this technique requires extensive experience to make an accurate diagnosis and needs to be carefully discussed with the clinical radiology department. The inevitable disadvantage of fine needle biopsy and FNA is that the sample volume is small, which not only affects the accuracy Diagnose and influence histological classification and other auxiliary diagnostic techniques such as cytogenetics and electron microscopy.
