Ganglion Cyst


A ganglion cyst is a fluid filled, noncancerous lump around the joints and tendons of usually the hands or feet. It may also appear around other joints of the body.

Causes are not very clear but they may include:

  • Injury or trauma
  • Overuse of the joint
  • Inadequate reabsorption of the fluid lubricating the joints and tendons


  • Firm lump that may change in size
  • Pain if the lump is touching a nerve
  • Lump may move a little when pushed

Some cysts disappear on their own and treatment is not required if they are painless. If symptoms are present, treatment may include:

  • Bracing or splinting to reduce the size by avoiding movement
  • Aspiration to remove the fluid with help of a needle
  • Excision to remove the cyst through surgery

There is no way to prevent ganglion cysts.
