A ganglion cyst is a sometimes painful, but benign bump that forms in the lining of a joint or tendon.  Ganglions are often found around the wrist or finger joints.

The cause that initiates the ganglion to form is unknown, however it is a chain reaction that causes the ganglion to grow.  A small opening occurs in the joint or tendon lining.  When the tissues are relaxed the opening relaxes letting fluid flow in and out.  When the tissues stretch the opening closes, creating a one way valve that traps the fluid inside.  The body starts to respond to this "bubble" of fluid and starts to enclose it with a substance called collagen.  Over time the fluid inside becomes thicker and gelatinous, thus creating a ganglion.

Ganglion cysts can take months to form depending on their location.  Often they remain undetected as long as they are not painful or restricting movement.

Ganglions are diagnosed by their characteristics and location.  Most ganglions grow during periods of increased activity.  Symptoms may include tingling in the hands and fingers, weak grip strength or pain caused from the ganglion pushing on nearby nerves.  In cases like these, medical attention is necessary.
