Ganglion cysts are common lumps within the hand and wrist that occur adjacent to joints or tendons. The most common areas they are found are the top of the wrist, the palm side of the wrist, the base of the finger on the palm side, and the top of the end joint of the finger.
These cysts originate from a joint or tendon and may change in size or even disappear completely, and they may or may not be painful. These cysts are not cancerous and will not spread to other areas.
An aspiration can be performed to remove the fluid from the cyst. This can be performed in most office settings. If non-surgical options fail to provide relief or if the cyst recurs, surgical alternatives are available.
