Ganglion Cyst

A ganglion cyst is a benign swelling filled with a jelly-like fluid that develops from the tissues surrounding joints or tendons. These cysts most often occur on the wrist or hand but may appear near other joints. They vary in size and may become larger or smaller over time. Many ganglion cysts cause no symptoms, but some may produce pain, discomfort, weakness, or pressure on nearby structures. Some disappear without treatment, while others may require medical evaluation if they cause problems.

A ganglion cyst is a harmless fluid-filled lump that usually appears near a wrist or joint. It may go away on its own or need treatment if it causes discomfort.
