Can playing piano cause ganglion cysts in the fingers or wrist?

There is no evidence associating repetitive light stress to the formation of these cysts (I'm assuming piano is light stress if you have a correct technique) or any stress for that matter (something like a gymnast or factory workers for example).

These are almost always considered idiopathic (no clear cause or trigger event) and can show / disappear at any time.

If you have a cyst though, you should test if movement of the hand or fingers produces pain - that is a not so good sign. In most cases it's painless and requires no treatment unless it keeps growing and changing.

There is a lot of anecdotes of pianists getting cysts from incorrect/stressful technique. Piano is defintely not just light stress if technique is wrong, as evidenced by the fact that you can injure yourself quite severely playing standard repertoire with wrong technique. And I wouldn't count on the average person having a fully correct technique.
