  • A ganglion cyst is a benign ball of fluid that grows on a tendon or joint.
  • The backs of the hands and wrists are most commonly affected, but ganglion cysts can also grow on the feet, knees and ankles.
  • The cause is unknown, but it is thought that small tears in the tendon membrane or joint capsule allow the contents to squeeze out.
  • In many cases, ganglion cysts go away by themselves without the need for medical treatment.
  • Treatment options include surgery or draining the cyst with a needle.
