Dr. Khurram Pervaiz answers your questions about ganglion cysts.
My doctor told me I have a “ganglion cyst.” What is that?
A ganglion “cyst” is a benign (not cancer) mass that can occur in the hand or wrist. The cyst is composed of a sac filled with fluid.
What causes a ganglion cyst?
No one knows exactly why this happens, but a defect in the joint capsule causes fluid to leak out into the soft tissues and cause the cyst.
What are some of the symptoms of a ganglion cyst?
Ganglion cysts can happen in different parts of the hand and wrist. They most commonly appear on the “back” of the wrist. They may also affect the palm side of the wrist, hand or fingers. They sometimes are attached to a finger tendon. A ganglion cyst can change in size. Some hurt, and others do not.
