Ganglion / Mucous cyst

A ganglion cyst, (mucous cyst in the fingers) also known as a Bible cyst, is a common swelling that often appears on or around joints and tendons in the hand or foot.The size of the cyst may vary over time, and can increase after activity. It is most frequently located around the dorsum of the wrist and on the fingers.

The most commonly accepted cause of ganglion cysts is the “herniation hypothesis”, in which they occur as “an out-pouching or distention of a weakened portion of a joint capsule or tendon sheath.


Prior to any treatment Mr Stanley Loo will assess your ganglion / mucous cyst at Eastcare Medical Specialist Centre and discuss the treatments which are best for you.

Surgical treatments remain the primary option, other than doing nothing at all, for the treatment of ganglion cysts.

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An outdated method of treating a ganglion cyst was to strike the lump with a large heavy book, causing the cyst to rupture and drain into the surrounding tissues.
