I first used this site a few weeks ago when I was waiting to take my mum to her first appointment with her gynaecologist after she was diagnosed with an ovarian cyst. At that appointment we discovered that the cyst on her ovary is 20cms by 12 cms. The consultant recommended a CT scan and I will be taking her for the results on Tuesday. Her CA 125 is 25. Will wwe be told on Tuesday if this is cancer or will they say that the next stage is a biopsy? In the meantime my sister who is 45 has been experiencing abdominal pain. She also has had ongoing problems with very heavy periods and increased need to urinate, Anyway following severe pain she was sent for an ultra sound scan and has been diagnosed with ba septated ovary, She is awaiting her CA125 results. Has anyone had any experience of this type of cyst? I am very worried about both of them at the minute.
