(Cyst, Ganglion; Ganglion)En Español (Spanish Version)
A ganglion cyst is a fluid-filled sac that is usually attached to either a tendon sheath or a joint lining. Ganglion cysts usually appear on the back of the wrist. They may also be on the underside of the wrist, the hand, the fingers, or the feet. Ganglion cysts are always noncancerous.

These factors increase your chance of developing a ganglion cyst. Tell your doctor if you have any of these risk factors:
- Sex: female
- Age: 20-50 years old
- Participating in gymnastics
- Appearance of a soft bump, usually on the back of the wrist
- Pain or tenderness at the site of the bump
The doctor will ask about your symptoms and medical history, and perform a physical exam. Most ganglion cysts are easily diagnosed based on the location and appearance. The doctor may use a small needle to remove some of the cyst's fluid for testing.
Other tests may include:
Some ganglion cysts go away without treatment. If the cyst is very tender or unsightly, you may want treatment. Even with treatment, ganglion cysts often return.
- Ibuprofen or aspirin to relieve pain and swelling
Note: Do not attempt to smash the cyst with a heavy object (a traditional home remedy). This is unlikely to get rid of the cyst and more likely to injure you.
You may need to wear a splint on your wrist. Ganglion cysts usually get smaller with less activity and larger with more activity.
A needle is put into the cyst to drain the fluid.
A steroid solution is injected into the cyst, which is usually done after the cyst is drained.
The cyst can be surgically removed. This is done when they are large and unsightly or painful. Cysts may return even after surgery.
