Ganglion

Ganglion cysts are soft, gel-like masses that often change size. They tend to be smooth and round, and are: the most common type of swelling in the hand, wrist and foot harmless and can safely be left alone

A ganglion cyst starts when the fluid leaks out of a joint or tendon tunnel and forms a swelling beneath the skin.

The cause of the leak is generally unknown, but may be due to trauma or underlying arthritis

Ganglions can form at the back or front of the wrist, base of fingers, on the finger. Approximately 80% of ganglions are found in the wrist.

About 50% of ganglions disappear on their own. You won’t need treatment unless the cyst is painful.

Surgery

If the ganglion hasn’t reduced in size after 6 months or is causing significant functional difficulty and/or pain, you may require surgery. However, there’s a chance it will come back even after surgery.
