A ganglion cyst is a fluid-filled sac. It is usually attached to the membrane that surrounds a tendon or a joint lining. Ganglion cysts usually appear on the back of the wrist. They may also be on the underside of the wrist, hand, fingers, or feet. Ganglion cysts are not cancerous.

Some ganglion cysts go away without treatment. If the cyst is tender or unsightly, treatment may be wanted. Even with treatment, ganglion cysts can return.
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, but it is likely to cause injury.
Because many ganglion cysts disappear on their own, watching it to make sure it is improving may be all that is needed.
A splint may need to be worn on the 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. This 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.
