It is necessary to do pathology after removal of liposarcoma. Liposarcoma is one of the malignant tumors that often occurs in the deep intermuscular soft tissues. Liposarcoma can be categorized into highly differentiated, mucinous, round cell and other types of liposarcoma, which may also differentiate and metastasize to other organs and tissues in the body, so it is also necessary to do pathology. Pathology is necessary because it can tell which type of liposarcoma it belongs to and whether or not the cells in the sarcoma have metastasized, which is helpful for the prognosis of the patient after the removal of the liposarcoma and for guiding the targeted treatment. If the pathology is not done, the prognosis may be poor. For patients after liposarcoma removal, treatment should be carried out under the guidance of doctors. Do not exert excessive pressure that will affect the outcome of the treatment.
