Uterine wall solid occupancy lesions can not be excluded may be caused by benign or malignant tumors. 1. Benign tumors: uterine wall solid occupancy is most commonly seen in uterine wall fibroids, or polyps, etc., generally recommended conservative treatment or elective surgical treatment, relatively speaking, the prognosis is relatively good. 2. Malignant tumors: if there is a substantial lesion, then we can not rule out the possibility of uterine wall sarcoma, which needs to be based on the size, scope and patient’s symptoms, and need to consult a doctor in a timely manner, choose the appropriate way of treatment. Tumors will occupy the original normal tissue position, so it is called occupying lesions. Occupying lesions do not indicate whether the tumor is benign or malignant, and the final decision should be made based on pathological findings. Occupying lesions of the uterine wall should be treated promptly for a clear diagnosis.
