What are Ganglion Cysts?

November 14, 2018

Ganglion cysts are lumps of fluid found along a tendon. They are most commonly located in the wrist and hand area or the ankle and foot. They are usually not painful and typically are simply a cosmetic issue. Cysts can vary in size from tiny to as large as an inch wide. They are usually harmless and not cancerous. These lumps usually don’t cause any pain and often resolve on their own.

Thought to be caused by repetitive stress to a tendon or joint which creates an outpouching of a cyst of fluid, ganglion cysts are seen in people who do repetitive movements with their hands, especially in factory workers. They more common in women and their exact cause is not fully known.

Treatment of a ganglion cyst involves taking a break from the offending activity if it causes pain, using a splint, injection of a steroid into the cyst, or surgical excision. Even after utilizing injections or undergoing surgery, the cyst can reoccur.
