r an appointment with a gyn. had a back injury about 5 weeks ago, diagnosed as strain of lumbar paraspinous muscle. It didn,t get any better with time, so I went to my follow-up, and was ordered to have a CT scan The scan shows an ovarian cyst, the size of a peach.I am waiting for an appointment with a Gyn. What are my chances of this being cancer? I am an active 69 year old. What would be the normal procedure for this? Can it be a non-invasive surgery?
