What Is a Ganglion Cyst on the Wrist?
A ganglion cyst is one of the most common causes of a visible lump on the wrist or hand. While the appearance can be concerning, ganglion cysts are benign, meaning they are not cancerous and are not dangerous. Still, they can cause discomfort or interfere with daily activities, which is why many patients seek evaluation and treatment.
In this blog, we explain what a wrist ganglion cyst is, why it forms, and what treatment options are available.
What Is a Ganglion Cyst?
A ganglion cyst is a firm, fluid-filled lump that typically appears on the front or back of the wrist, though it can also develop on the hand or fingers. These cysts arise near joints or tendons and are filled with a thick, jelly-like fluid.
One unique feature of ganglion cysts is that their size can change. They may become larger or smaller over days or weeks, and sometimes they seem to disappear altogether before returning later.
What Causes Ganglion Cysts?
The exact cause of ganglion cysts is not fully understood. They are believed to develop when joint or tendon fluid leaks out and collects into a small sac. Although they can occur after repetitive use or injury, many cysts form without a clear trigger.
Importantly, ganglion cysts are not dangerous and do not spread.
Symptoms of a Wrist Ganglion Cyst
Some ganglion cysts cause no symptoms other than a visible bump. Others can be bothersome or painful, especially if they press on nearby nerves or limit wrist movement.
Common symptoms include:
A noticeable lump on the wrist or hand
Wrist pain or aching
Tenderness when pressure is applied
Reduced range of motion
Tingling or numbness if a nerve is affected
Do Ganglion Cysts Need Treatment?
Not always. If a ganglion cyst is painless and not interfering with function, one option is simply to leave it alone and monitor it over time.
When symptoms develop, treatment may be recommended.
Treatment Options for Ganglion Cysts
Aspiration or Drainage
In some cases, the cyst can be aspirated, meaning the fluid is drained using a needle during an in-office visit. This can relieve pressure and reduce pain. However, cysts can sometimes return after aspiration.
Repeat Drainage
If a cyst recurs after aspiration, it may be drained again, depending on symptoms and location.
Surgical Removal
For cysts that repeatedly return or cause ongoing discomfort, surgical excision may be recommended. This outpatient procedure is performed in the operating room, and patients typically go home the same day.
Most people recover within 3 to 4 weeks, and the likelihood of the cyst returning after surgical removal is very low.
When to See an Orthopedic Specialist
If you have a wrist lump that is painful, growing, or affecting your daily activities, an orthopedic evaluation can help confirm the diagnosis and guide treatment. Imaging or physical examination can determine whether the bump is a ganglion cyst or another condition.
