Ganglion

A ganglion is a very common harmless cyst that grows under the skin of the hand, wrist, or foot. They are generally found on the top or palm side of the wrist, at the end joint of a finger, and at the base of a finger. A ganglion cyst rises from a joint or tendon sheath and has a jelly-like fluid in it. A ganglion never turns into cancer. We do not know why ganglions develop. In some cases, there has been a history of an injury or repetitive stress.

When ganglion cysts first appear they can be painful. Usually, they are painless and can change in size. Most ganglions do not need any treatment. Some may even go away without any treatment. If there is pain or restricted movement to the affected area, the ganglion may need to be removed.

A ganglion cyst that is painful, limits activity, or is unsightly can be removed. A medical evaluation by a healthcare provider will determine the appropriate method of removal, draining the fluid from the cyst or performing minor surgery. The outpatient surgery procedure removes the cyst and its source. Recovery may take a few days to one week. Since there is no way to prevent ganglions, the cyst may return after either removal procedure.
