Complex ovarian cyst

2 Nov 2017 06:41

Hello everyone,

i have just been diagnosed with a ‘mildly’ complex 2.7 by 2.1 ovarian cyst. ( I’m not sure how something can be mild & complex but that’s how it’s described)

my only symptom is  one incident of post menopause bleeding, which is why my GP referred me for an ultrasound. I am now awaiting the results of a ca125? blood test but I’m out of my mind with worry. 

No risk factors for OC & none of the main symptoms, but still convinced I now have cancer. 

Any advice greatly appreciated.


thank you x

Hello Bridget and thanks for your post

When cysts are seen on a scan they are either simple or complex. Simple cysts are thin walled and only contain fluid. These are not cancerous. A complex ovarian cyst can raise a suspicion of malignancy and so usually needs to be assessed further. But as well as the look of a cyst, the risk of cancer is assessed by other things like the CA 125. So although there may be a suspicion of malignancy, it is by no means a certainty.

I realise waiting for results when you are worried is stressful. But hopefully it won’t be too long until the results of the CA 125 test are back and your doctors can tell you more.

I hope you know more about your situation soon. If you would like to speak to one of the nurses to talk this through further, you can telephone us on 0808 800 4040.  We are here from Monday to Friday, 9am-5pm.

Best wishes,

Hi Happy

my CA125 came back negative so just wondering how reassured I should be by that? My doctor said it was good news but I’m still finding it hard not to panic. 

I have another scan tomorrow to see if the cyst has changed in anyway. 


Any advice appreciated.

Hello Bridget15,

Thank you for getting back to us with another question.

I am very pleased to learn that  your CA125 blood test result came back within the normal range.. This makes it unlikely that anything too serious is wrong.  But very occasionally a woman with a normal CA125 will have ovarian cancer. So a normal test cannot rule it out completely.

Waiting for tests investigations and the results can be very stressful, hopefully you will soon know a little more about your situation. And I hope that it goes well for you.

All the best,
