They are not generally considered harmful although can cause discomfort and/or limit movement. Frequently, the cysts will disappear over time, so in cases of small cysts that don't cause symptoms, no therapy is necessary. If a ganglion cyst is symptomatic, it can be managed by aspiration or surgery. Aspiration of the cyst is simpler method, but cysts will develop again in about 50% cases. Recurrence rate after surgery is only 5-10%, the procedure is simple and usually there are no complications.[/b]
