Scared so much. Large complex ovarian cyst

Hi all. I've been having a bloated stomach for a few months. I had to call an ambulance Friday due to hurrendous pulling pain in stomach area. To cut a long story short, they scanned me and have found a 15cm complex cyst. And 2 peritoneal nodules. Not sure if they are linked at all. My is it? (CA 125 levels were elevated but not high, think they were 50? Gynae said they can be in the thousands with cancer. I have been fast tracked for a chest scan and a biopsy of these nodules. Can anyone help? Thanks
