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:
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:
—a test that uses radiation to take a picture of structures inside the body, especially bones
—a test that uses magnetic waves to make pictures of structures inside the affected area
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.
