I have tried to copy and paste details of my experience for your info hope it helps (if it works).

Slightly different circumstances . I was rushed into hospital a few years ago as an emergency with excruciating pelvic pain misdiagnosed and sent home . Trying to make along story short . I was then contacted to return to hospital for a ct scan or mri can’t remember which and kept in hospital. Apparently should not of been sent home . After a difficult time in hospital after a week transferred to another hospital caught Covid during 2022 covid was still about sent home again to be treated as an out patient, (not happy) I think what I’m trying to say is out patient appointment was when I was told I had a ca125 level of 161 and a large ovarian mass . Surgery was needed as a matter of urgency as the mass was large and cutting off my blood supply . Surgery eventually completed with mass removed and full hysterectomy. The mass was a large ovarian fibroma 14-11-7cm and benign . I never understood the ca125 thing being so high but thankful for a good outcome .

It was not a very nice experience in hospital . I was transferred to another hospital with more  gynae options but when transferred caught Covid so it was almost as if can’t do much because of the Covid .  I attended the outpatient appointment and fortunately saw a fabulous consultant who explained everything to me (which was not done in hospital) . The priority was me and although the wait for surgery was a long one nothing was going to delay it any longer. In fact the surgery was bought forward as my sister paid for me to go private even then the hospital was concerned due to having had Covid but the consultant wasn’t having any of it and surgery went ahead even sooner .
