vaginapagina | endocervical cells? (Reply)

my roommate has gone for a pap smear twice already. the first time they didn't get enough cells so she went back again, and the same thing happened. she just talked to her gyno today who said she didn't have enough endocervical cells. what does this mean? (besides "..she doesn't have enough cells" ;) ) ..they said because she isn't sexually active and not a smoker blahblah, it's not a big deal and she can just wait until next year for her next pap smear.

has anyone else has this happen to them and do they know why it happens? if you have any answers for her she'd really appreciate it. thank you.
