Had cone biopsy done cam back cervical carcinoma in situ w/clear margins. first abnormal pap ever with regular paps. what is chance of it coming back?

Cervical CIS: In theory, if the cone procedure came back with "clear margins, " the cancer is cured. Clearly, your gynecologist has recommended yearly pap smears, probably through age 65, to follow up. If a post-procedure pap smear was positive, your doctor will recommend further treatment.

None but repeat PAP,: This should not "come back" as the margins are clear, but you need to keep doing your paps. You need to follow up with a pap next year, and every year unless you get 2 consecutive negative paps, and then you can do the next in 3 years. Again, keep getting your paps.
