I am a 42 year old who had a hysterectomy almost two years ago...I have had cysts on my ovaries in the past, one which burst. I have been having pain in my left hip, so I had an MRI done. There were no findings on my hip; however, they did see a 5cm cyst on my right ovary. Is this dangerous, will I need surgery? When I had the hysterectomy I asked the doctor to please remove my ovaries for fear of this reason.
