i wish i could be of more help.
you might consider another appt with this dr and bring someone with you who can be a 2nd set of ears. that person can also ask Q's and write down what the dr says while you're there.

i'd get the non-surgical tests done first. like pap smear, endoscopy etc.
get copies of all these tests and the results and start keeping a file on yourself. also, ask for copies of the dr's dictation. you'll learn a lot.
you may have to sign a release but you have a right to the info. do this as you go along as the copies will be free. if you wait and ask for 2 mos worth they will charge you copying fees.

you might also want to discuss all this with your pcp. your dr should be able to condense this info in terms you can understand and help you with referrals and to coordinate the care you need.

sending prayers you way.
please keep us posted.
