Ganglion cysts

Ganglion cysts are the commonest type of swelling in the hand and wrist. They contain a thick clear fluid.

Most ganglion cysts arise randomly but occasionally there is a history of injury or the joint underneath may have some arthritis.

Ganglion cysts are harmless and can safely be left alone. Many disappear spontaneously and many others cause little trouble.

There are no long term consequences from leaving the ganglion untreated.

If you have a lump which is painful or getting larger, please see your GP.
