I believe that although values vary in different labs your ca125 is considered a problem if its over 35/40. I also had cysts picked up last year - largest one 4.5cms - so I had the ca125 test and I believe my level was ten, which they said was good news. And I had another scan 3 months later and the cysts had vanished, which the docs and nurses all said was what usually happens, they just sort of ebb and flow. However obviously I can't give you medical advice - I realise you are probably sick and tired of going to the doctors but why don't you see your GP to have your mind put at rest. They ought to know what it means. And what did this registrar who is obviously rather lacking in bedside manner say should happen next? If s/hes concerned then clearly s/he needs to investigate further, but personally I agree with your verdict that s/he's talking a load of old pants.
