Ganglion
Ganglion
A ganglion is a small sac filled with fluid and is usually attached to the lining of a joint or tendon. Ganglion forms when tissues surrounding certain joints become inflamed and swell up with lubricating fluid. They are most common in women nearly 3 times and 70% occur in the late teens and young adulthood. Most commonly, ganglions are seen on the wrist (usually the back side) and fingers, but they can also develop on the shoulder, elbow, and knee. They can increase in size or can disappear spontaneously. These masses or cysts, however, are not tumors or non-cancerous. Ganglions are usually painless. However, the condition can become painful when the ganglion presses nerves. This pain can restrict the range of movements and activity of an individual.
