I know that my surgeon would never indicate that I had a cyst and not aspirate it. The only way they can tell if it is a cyst is to aspirate it. Most doctors will send the fluid out for biopsy. Once aspirated, it falls in on itself and usually goes away.
It is when they cannot aspirate it that it becomes a little more important. I agree with Deb, get all your films and find another dr. I don't know what's up with some drs today. I think you're handling the situation pretty well. I would be very unpleasant to some of the people you are having to deal with. That's why some of my drs cringe when I have an appointment.
Sorry you're here and hope you don't stay long.
