Ganglion Cyst

Prevention

Because the cause of a ganglion cyst is not known, it is difficult to tell how to prevent them. Early evaluation and treatment are recommended.

Outlook

Because this is a harmless tumor that can go away on its own, or after a simple needle aspiration or minor surgery, chances are good that you will have a full recovery. Because ganglion cysts may come back after any of these treatments, however, a single treatment may not be enough.
