A ganglion cyst is a fluid-filled lump that forms from a joint or tendon sheath.
Not sure what you've got? Most are harmless — but not every lump is a ganglion cyst. Other types of lumps can look similar. That's why proper assessment matters.
The exact cause isn't always clear, but it is linked to joint and tendon irritation rather than any lifestyle factor or deficiency.
Common myth: Ganglion cysts are not caused by vitamin deficiency. Despite what you may have read online, there is no nutritional link. They arise from mechanical or structural factors affecting the joint capsule.
Chronic stress or irritation of the joint capsule can cause synovial fluid to escape and pool.
Repeated wrist movements — particularly in work or sport — may increase susceptibility.
A weakness or defect in the joint capsule allows fluid to herniate through, forming the cyst.
Cysts can also arise from the tendon sheath — particularly in the fingers and palmar surface.
Ganglion cysts most commonly form around the wrist and hand, though they can occur at any joint or tendon sheath throughout the body.
We hear these every day. Here's what you need to know before you worry any further.
In the vast majority of cases, ganglion cysts are benign (non-cancerous). They are not dangerous, but proper assessment confirms this with certainty.
If a ganglion cyst ruptures internally, the fluid is usually reabsorbed by the body and the cyst may resolve naturally. It is rarely a medical emergency.
Other lumps can closely resemble a ganglion cyst. Lipomas, nerve sheath tumours, and other lesions require different management — this is why diagnosis matters.
If you're searching "how to drain a ganglion cyst yourself" or "remove at home" — stop for a moment. The old "hit it with a book" method is exactly as unsafe as it sounds. Draining it yourself risks serious complications.
In many cases, there’s no single cause — it develops gradually
Not every ganglion cyst needs removal. Here is our honest, evidence-based approach from initial assessment to recovery.
Confirms your diagnosis, and guides the right treatment decision. Quick, accurate, and consultant-led. Ultrasound is the gold standard for cyst assessment
Needle drainage performed in clinic. Quick and minimally invasive with immediate results. Note: recurrence rates are higher compared to surgical excision — typically 40–70% recurrence after aspiration alone.
These can relieve symptoms, especially early on.
Day-case procedure under local anaesthetic. The entire cyst and its root are removed, resulting in the lowest recurrence rate of all treatment options — approximately 5–15% vs 40–70% for aspiration.
~5–15% recurrence · Day-case
Simple recovery with gradual return to normal activities. Follow-up support is included in your care. Most patients return to desk work within a few days and manual work within 1–2 weeks.
Follow-up included · No hidden costs
No hidden costs. No surprises. You'll know exactly what you're paying before committing to any treatment.
Diagnostic ultrasound to confirm diagnosis and assess cyst characteristics.
Consultant-led assessment, history review, clinical examination, management plan.
In-clinic needle drainage under local anaesthetic. Quick and minimally invasive.
Day-case excision surgery. Lowest recurrence rate. Local anaesthetic. Follow-up included.
