Common masses or lumps that grow in the hand or wrist are called ganglion cysts. These may be found on top of the wrist, palm side of the wrist, base of the finger, or the end of the finger joint. While no specific cause has been identified, these are still painful and may change in size or disappear. They are not, however, cancerous. The diagnosis made is based on location, size and appearance. Treatment may vary from simply observing the cyst for changes, to removing fluid from it with a needle. You may be required to wear a splint for a period of time, or surgery may be required to remove the cyst. The primary goal of surgery is to remove the source of the cyst. This may include removal of the joint capsule or tendon sheath next to the cyst. There may be swelling and discomfort, and a splint may also be applied following surgery. Cysts may return at later dates. The surgeons and staff at The Face & Body Center are available to discuss any questions you may have by calling 866-939-4999 or 939-9999 in the Jackson Metro Area.
