Patients with cysts in the maxilla usually do not have the possibility of cancer. However, if the cyst in the maxilla is repeatedly infected and frequently stimulated by inflammation, it may easily become cancerous. Therefore, it is recommended that if the cyst is not infected, the cyst in the maxilla should be removed by surgery, which can effectively improve the clinical symptoms and reduce the chance of cyst infection and the possibility of cancer. When the maxillary cyst is small, the surgery is less traumatic for the patient and easier to operate. When the cyst grows up or is often infected, the surgery is more traumatic for the patient, so it is recommended that the patient actively go to the hospital for surgery.
