Trust your doctor, if they saw something was that bad, they wouldn't have told you to wait for six months. I'm sure there are lots of benign reasons for your test results, and as you have no symptoms, you really needn't worry so much! I know how horrible health anxiety is, and I'm sorry you're going through these fears. *hugs*
