Malignant cysts are more serious, and there are benign and malignant cysts. Benign cysts grow slowly and generally have less impact on the body, while malignant cysts grow rapidly and can metastasize, potentially affecting the patient’s health and even endangering the patient’s life. Cysts can grow in many parts of the body, such as ovarian cysts, which often occur in women. Many cysts are benign and have a relatively small impact on the body, but in the case of larger cysts, there may be symptoms of pressure on the corresponding area. Surgical treatment can be performed and a cure can be achieved through surgery, but some cysts may have the possibility of malignant transformation. Malignant cysts, need to be treated in time because they grow faster and once they metastasize, they can endanger the patient’s life. Therefore, once a malignant cyst is diagnosed, patients with indications for surgery should undergo surgery in a timely manner. After surgical removal of the cyst, and pathological examination, according to the type of pathology, choose the appropriate chemotherapy plan, chemotherapy or radiotherapy to prolong the patient’s life and relieve the patient’s pain.
