Ganglion Cyst

A ganglion cyst is a fluid-filled sac that most commonly forms along the tendons or joints of the wrist or hand. These noncancerous lumps can appear suddenly, change size, or disappear entirely on their own, and are among the most common soft-tissue masses of the hand and wrist.

• A visible, round or oval lump, often on the back of the wrist
• Dull ache or pressure, especially with wrist motion
• A lump that changes size over time – In some cases, no pain at all, purely a cosmetic concern

The exact cause is not always clear, but ganglion cysts are thought to develop from a weak spot in a joint capsule or tendon sheath, allowing joint fluid to accumulate. They’re more common in people ages 20–40 and occur more frequently in women.

Observation, since many ganglion cysts resolve without treatment – Aspiration (draining the cyst with a needle) – Splinting to reduce irritation – Surgical excision for persistent, painful, or recurrent cysts

We take a conservative-first approach whenever appropriate, reserving surgery for cysts that are painful, limiting function, or repeatedly recurring, always with a clear explanation of your options.
