Personnally, I would be adamant about getting a CT scan.
I don't know your situation, but a pap can't determine if there is anything going on internally.
More importantly, you need to ask your doctor ALL your questions. Write them down so that you remember everything. If you don't feel comfortable talking to the doctor or you don't feel that she is giving you the time you need, then find a new doctor.
It's SO important to trust your doctor. I just changed doctors and went to a completely different hospital system. You need to feel confident that your doctor is doing everything possible to keep you healthy.
It's your life we are talking about!
Unfortunately, it took a recurrence for me to realize all this.
I think when you have initial shock of a diagnosis you will do whatever someone tells you. In hindsite, I should have made sure I was comfortable with everything in the first place.
Good luck and take care.
Please take the time to be your own advocate!
