A ganglion cyst on the wrist with synovial fluid may appear quickly and can also disappear just as suddenly. It may also change its size and may also not require any treatment. But some ganglion cysts do require non-surgical or even surgical intervention. This is particularly required when the cyst in painful or it interferes with normal functioning or has an unacceptable appearance.
A ganglion cyst which develops on the top or underside of the wrist may grow larger with wrist activity. If the wrist is given rest, the lump generally grows smaller in size.
