Pelvic mesenchymal tumors are tumors from mesenchymal tissues, including benign tumors and malignant tumors, and the specific treatment plan includes surgical treatment, radiotherapy treatment and daily care. 1. Benign tumors: for benign lesions, radical resection can be done through surgery, and after surgical resection, a large part of them can be clinically cured; after surgery, we should pay attention to controlling diet, avoiding spicy and stimulating food, and deep heat therapy can be carried out, which can help wound recovery. 2. Malignant tumors: early malignant tumors need radical resection through surgery, postoperative adjuvant radiotherapy and so on according to the situation. In advanced stage, palliative radiotherapy and other treatments are feasible to prolong the survival and improve the quality of life. Pelvic mesenchymal tumors should be found in a timely manner to seek medical treatment and early treatment to avoid progression of the disease.
