Yes they are actually more normal than we realise even in menopausal women, I also have one, it all depends on how big it is and what the scan shows, they are usually harmless fluid filled cyst which can be left alone, surgical intervention is only really warranted if they have go very big or are causing discomfort or if they look a bit suspect on the scan, try not to stress, how do you know that you have a cyst if you have not had your scan yet?
