Bone cysts do not usually lead to cancer. Bone cysts are cyst-like confined lesions that occur inside the bone, and their cause has not been clearly defined. Bone cysts can be divided into two types: unicompartmental bone cysts and aneurysmal bone cysts. Usually, bone cysts are very unlikely to become malignant and do not lead to cancer. After suffering from this disease, there are usually no obvious symptoms. Patients with bone cysts are mainly treated by surgery, during which the fibrous envelope should be scraped off thoroughly to prevent recurrence. The prognosis is good, and cancer will not occur in general. Patients with bone cysts should go to the hospital in time and adopt appropriate methods for treatment.
