Hi to everyone on this site. I have a doubt ...apparently the age for starting Pap smears has change. The way i learned on Kaplan was that you have to start doing Pap smear was at 18 y/o or at the beggining of sexual intercourse. I just did a question on the USMLEworld that deals with this subject and it says that now you start at 21 y/o or 3 years after you begin sexual intercourse. I investigated on The American Cancer Society site and apparently it really has change. This question could come on the step 2 and my question is, should i listen to USMLE world better or keep Kaplan guidelines?...well i hope this helps other people too.
