The cause of vaginal mucosal swelling is unknown. It is a malignant tumor of soft tissue composed of variously differentiated rhabdomyoblasts. The disease may be associated with genetic factors, chromosomal abnormalities, and gene fusions. Rhabdomyosarcoma is mainly resected surgically, including the entire muscle where the tumor is located. For embryonal rhabdomyosarcoma, in addition to resection, chemotherapy and radiotherapy should be combined to relieve symptoms. Prevention is mainly to improve the body’s ability to prevent cancer and to do a good job in tertiary prevention of cancer. So what should be done exactly? Tertiary prevention (rehabilitation prevention) is the rehabilitation work for patients after cancer surgery, so as to reduce complications, prevent disability, improve survival rate and enhance survival quality. All of them are organized by medical personnel to give physical, psychological, labor and life counseling to patients, and make follow-up records to observe their long-term efficacy, and to give patients mutual comfort and care for each other, and encourage them to fight against cancer together, and also accumulate rich information for clinical research.
