Should I have a ganglion cyst removed?

In short

A ganglion cyst only needs removing when it hurts, limits how the wrist works, or its makeup is unclear. The lump on its own is not a reason to operate. At The Hand and Wrist Institute, Dr. Knight starts with activity change and a brace, and surgery comes last.

What a ganglion cyst is

Put your other hand over the back of your wrist and press gently on the bump. What you are feeling is a sac of thick fluid, or what we call a ganglion cyst, that has grown out of the joint underneath on a short stalk.¹ They sit most often on the back of the wrist, and also on the palm side, at the base of a finger, and out near the fingernail.¹ Size is a poor guide to how much trouble one is causing, and the same cyst can swell through a heavy week of work and settle again with rest.

Draining a cyst and removing a cyst are two different things

People say "getting it taken care of" for both, and they are not the same procedure. Drawing the fluid out through a needle, or what we call aspiration, empties the sac and leaves the sac wall and its stalk where they are. Removal means taking the sac out at the root, down at the wrist joint, so the whole thing is gone and the tissue can be sent to a pathologist.¹ Here is the test you can apply before you agree to anything. Ask which of the two is being offered, and ask whether the tissue goes to the lab afterward. Dr. Knight has stated his own position on aspiration on video, and it is quoted below in his words.

The order Dr. Knight works in

1. Change what aggravates it. Most people notice a wrist ganglion on pushing motions, so the first move is to take the load off those positions and see whether the cyst settles.
2. Brace and anti-inflammatory. Resting the wrist in a brace, particularly at night while you sleep, alongside an anti-inflammatory such as ibuprofen, is the next rung.
3. Draw the fluid out. Aspiration through a needle is an option at this stage, and a cyst treated this way can come back.¹
4. Remove the cyst. This comes last, and it is the step that also produces a tissue sample. Dr. Knight performs it under a general anesthetic so the wrist is still, and he frequently puts a small camera into the joint at the same time to look at the ligaments and the cartilage.

Some ganglion cysts settle on their own and never need any of this.¹

When to call us

• The lump grows steadily instead of changing size with activity and rest.
• You have numbness, pins and needles, or weakness in the fingers on that side.
• The wrist pain stops you gripping, pushing off a chair, or sleeping.
• The lump is firm and fixed in place rather than soft and movable.
• The skin over the lump changes colour, breaks open, or drains.
