What Does Exploding Or Imploding Cysts Mean?

well just about two weeks ago I ve noticed that my stomach is swollen, and I have rumbling in my stomach constently. im urinating all the time, also my bowels have changed. very uncomfortable. I thought it s due to my increase in appetite. but my feeling is something else is wrong. I ve had hernia surgery twice, and my gal bladder out two years ago. I had a full body scan and the dr. said that I had exploding or imploding cysts. I don t know what that means. also degenerative joint disease in my left hip. what could be happening? I have a history of cancer in my family. my email address is YYYY@YYYY
