If a ganglion cyst is left untreated will it become very bad and serious?

Answer 1

I have a ganglion cyst in my wrist. Ganglion cysts are not harmful at all- the liquid inside of them is not toxic and the cyst is usually flexible enough to fit around bones and veins around them (in fact, my vein actually created a dent in the cyst because the cyst developed under the vein; however, the cyst isn't strong enough to break or even move the vein). Ganglion cysts rarely hurt and never restrict movement. Left untreated, the only thing a cyst might do is grow and shrink, which is perfectly normal. A ganglion cyst won't become serious. The only reason one might want to get rid of cyst (whether by a doctor draining or performing surgery on it) is for purely cosmetic reasons.
