Can ovarian cysts cause breast pain?

Yes: But unlikely. There is a certain type of ovarian cyst that causes overproduction of estrogen and that could cause breast pain, though those cysts are unlikely. It's more likely that the 2 are unrelated. I don't see your age, so it's difficult to say why you're having breast pain, but most common is due to hormonal reasons, typically cyclical. If you feel a mass, go to doctor right away.
