I've seen a lot of posts recently about these.
I had a benign cyst which was monitored for 2 years. When I had this it made me do some research into OC and I came across this site-
www.ovacome.org.uk
I really recommend that if you have any queries you read the site and espcially the page about BEAT it- on left hand side of menu bar. It shows a chart so you can list any symptoms before you see your GP.
HTH.
