A ganglion cyst usually looks like a lump or bump on your wrist, finger or foot. This lump may look symmetrical (round) or misshapen (more like an oval). A ganglion cyst sits just below your skin’s surface. It may look like a bubble blown from a joint. Ganglia sometimes have a translucent effect (you can see through the lump at certain angles).

A ganglion cyst is a firm, fluid-filled lump that can form in the wrist or hand. It grows from normal tissue in the wrist and fingers, and ranges in size from a pea to a peach pit. Ganglion cysts are not cancerous and not spread to other body areas. Ganglion cysts can appear suddenly or gradually over time.

A ganglion cyst is a lump, typically round or oval, that can develop on the hand or wrist. It may be as small as a pea or it can grow up to about an inch in diameter. Generally speaking, ganglion cysts are nothing to worry about. Fairly common, they are usually harmless, aren’t cancerous, don’t spread, and often disappear on their own.
