I get ovarian cyst at least 1x year, they are at least 5+ cm. I have had one of my ovaries removed, should I get the other one removed also?

Probably not. This is a problem that requires a face-to-face meeting with your doctor. In that meeting, your doctor will listen to you, perform a throrough examination and possibly order labs or other tests. Based on this information, he/she will be able to tell you what's wrong and what to do about it.
