I had CIN3 show up on my very first pap smear at age of 23 (yes slack naughty I know), I freaked out and thought I was going to die as u do when you only half listen to what is being explained as you are freaking out! GP clinic rang and said she wanted to see me the next day so 2 days after she had done pap smear, anyway I went to a clinic and they did a colposcopy and watched it every 3 months and it actually went away after 18 months, I then had pap smears every 6 months for 1 year and then yearly for 2 years and then back to 2 yearly.

Good luck to your friend
