A ganglion cyst is a fluid-filled swelling that commonly develops around a joint or tendon.
Ganglion cysts are particularly common around the wrist and hand.
Some are painless and require no treatment. Others can cause discomfort, pressure, weakness or restriction of movement.
A consultation can determine whether observation, aspiration or surgical treatment is appropriate.
What Does a Ganglion Cyst Feel Like?
A ganglion may present as:
A visible lump
A firm or soft swelling
Pain with movement
Pressure or discomfort
A lump that changes in size
Reduced movement in some cases
The appearance and symptoms depend on the location.
When Does a Ganglion Need Treatment?
Treatment may be considered if the cyst:
Causes persistent pain
Interferes with movement
Causes pressure symptoms
Recurs
Is functionally troublesome
Creates significant concern after assessment
Some ganglion cysts can simply be monitored.
Diagnosis
Diagnosis usually involves clinical assessment.
Imaging may be considered when the diagnosis is uncertain or when further information is required.

Prior to any treatment Mr Stanley Loo will assess your ganglion / mucous cyst at Auckland Plastic Surgery Group, Unit 6 / 31 Highbrook Drive, Highbrook, Auckland 2013 and discuss the treatments which are best for you.
Treatment depends on the cyst and its location.
Surgical treatments remain the primary option, other than doing nothing at all, for the treatment of ganglion cysts.
Surgery aims to remove the cyst and its connection to the underlying joint or tendon sheath where appropriate.
Alternatively, a needle may be used to drain the fluid from the cyst (aspiration); however, if the fluid has become thick owing to the passage of time, this treatment is not always effective.
An outdated method of treating a ganglion cyst was to strike the lump with a large heavy book, causing the cyst to rupture and drain into the surrounding tissues.
Ganglion Cyst Surgery
Surgical treatment is planned according to the location of the cyst.
Because important nerves, blood vessels, tendons and joints can be located nearby, careful surgical planning is important.
Recovery
Recovery depends on the size and location of the cyst and the extent of surgery.
Patients may experience temporary swelling, tenderness and restricted movement.
Hand movement and activity are progressively increased according to the surgeon’s advice.
Can Ganglion Cysts Come Back?
Yes. Recurrence is possible even after surgical excision.
This is an important consideration before treatment.
FAQs
Are ganglion cysts cancerous?
Ganglion cysts are benign fluid-filled lesions and are not cancer.
Can a ganglion disappear without treatment?
Some ganglion cysts can change size or resolve, so observation may be appropriate in selected patients.
Should every ganglion cyst be removed?
No. Treatment depends on symptoms, location and individual circumstances.
Can ganglion cysts return after surgery?
Yes. Recurrence is possible.
Where do ganglion cysts commonly occur?
They frequently occur around the wrist and hand.
