Hi I have recently been diagnosed with a large ovarian cyst. I am 49 years of age. CA125 came back normal. MRI and US also look as if nothing sinister. The gynaecologist wants to remove cyst and tubes and ovaries. I do not want to have the operation as I am concerned about long term implications of loss of ovaries. The gynaecologist was quite dismissive of their function at my age. There is family history of strokes and heart disease.
