A ganglion cyst in the wrist is caused by fluid leaking from a joint or tendon sheath and collecting in a small sac under the skin. The exact cause is not always clear, but it is often linked to joint or tendon irritation, repetitive wrist use, or minor trauma.
Causes of a ganglion cyst in the wrist
Ganglion cysts develop when synovial fluid (the lubricating fluid in joints) escapes and forms a cyst-like swelling. Common contributing factors include:
1. Joint or tendon irritation
Repetitive wrist movements or strain may contribute to cyst formation over time.
2. Minor injury or trauma
A previous wrist injury may weaken the joint or tendon lining, allowing fluid to leak.
3. Natural joint changes
Some cysts develop without any obvious cause and may be related to normal joint wear and tear.
4. Increased joint fluid production
The joint may produce excess synovial fluid, which can accumulate and form a cyst.
Are ganglion cysts dangerous?
Ganglion cysts are non-cancerous and not harmful, but they can become problematic if they:
- Cause pain or discomfort
- Press on nearby nerves
- Limit wrist movement
- Increase in size
