Understanding Ganglion Cysts
A soft, fluid-filled lump that appears near a joint or tendon in the wrist or hand is usually a ganglion cyst, one of the most common non-cancerous growths affecting this area.
While often painless, ganglion cysts can sometimes cause discomfort or restrict movement depending on their size and location.
Our clinic offers evaluation and treatment for ganglion cysts to relieve symptoms and address cosmetic concerns.
What Is a Ganglion Cyst?
Ganglion cysts form when fluid from a joint or tendon sheath leaks out and collects within a thin-walled sac beneath the skin, most commonly on the back of the wrist.
Although their exact cause isn't always clear, they're thought to develop from small areas of weakness in the joint capsule or tendon lining, sometimes following repetitive strain or minor injury.
Common Locations and Triggers
The back of the wrist, the most frequent site for ganglion cysts
The palm side of the wrist, near the radial artery
The base of the fingers, along the tendon sheath
Repetitive wrist strain or previous minor wrist injury
Symptoms of a Ganglion Cyst
- A soft, round lump that may change size over time
- Mild aching or discomfort, particularly with wrist movement
- Occasional tingling if the cyst presses on a nearby nerve
- Usually no pain at all, especially with smaller cysts
Treatment Options for Ganglion Cysts
Structured clinical options focus on symptom relief and cyst management:
- Observation – many cysts shrink or resolve on their own over time
- Splinting – reduces irritation from repetitive wrist movement
- Aspiration – draining the fluid to reduce the cyst's size
- Surgical excision – removes the cyst and its stalk for cases that recur or cause persistent symptoms
Frequently Asked Questions
Are ganglion cysts dangerous?
No, they are benign, non-cancerous growths and are not considered dangerous, though persistent or painful cysts should still be evaluated.
Will a ganglion cyst go away on its own?
Many do shrink or disappear without treatment, though some persist or recur, particularly if the underlying joint or tendon irritation continues.
Is aspirating a ganglion cyst a permanent solution?
Not always; cysts can recur after aspiration since the underlying connection to the joint or tendon sheath often remains, whereas surgical removal has a lower recurrence rate.
