What does an abnormal Pap smear mean?
Last updated September 3, 2026.
Usually not cancer - an abnormal Pap means cell changes worth a closer look, and the most common cause is HPV. MedlinePlus draws the key line: a Pap can show abnormal cells exist but cannot diagnose them. The follow-up - a repeat test, an HPV test, or a colposcopy with biopsy - supplies the actual answer. Most abnormal results are minor changes that clear on their own or precancers that are highly treatable when caught.
What to do
- Do not panic, do not skip. The dangerous response to an abnormal Pap is ignoring the follow-up, not the result itself.
- Ask which follow-up applies. Repeat Pap, HPV testing, or colposcopy - the path depends on the specific result.
- Know HPV is near-universal. Most sexually active people encounter it; the body clears most infections on its own.
- Keep screening after treatment. Treated precancer still calls for the surveillance schedule your provider sets.
