The short explanation
ASCUS stands for atypical squamous cells of undetermined significance. In plain words, the lab saw some cells that did not look completely normal, but the changes were too mild or unclear to call them a definite abnormality. It is the most common abnormal Pap result, and in most women it does not lead to anything serious. The usual next step is to find out whether high-risk HPV is present. Many labs test the same sample automatically. If HPV is negative, routine screening usually continues. If it is positive, a colposcopy, a closer look at the cervix, is often advised.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Infection, inflammation, recent sex or a vaginal cream can make cells look slightly unusual, and after menopause thinning tissue can do the same.
- Your age and previous results also change the plan. A younger woman with no history may simply repeat the test, while someone with earlier abnormal results may be sent for colposcopy sooner.
- An ASCUS result is not a cancer result.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you what your cells actually show or what your next step should be. That depends on your HPV result and history.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Was my sample tested for HPV, and what was the result?
- Do I need a repeat test or a colposcopy?
- Could infection or inflammation explain the change?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Book an appointment soon
- See a clinician within a few days if you have bleeding after sex, bleeding between periods or a new unusual discharge.
Raise it at a routine appointment
- Book a follow-up visit to go through the full report and agree on the next step and its date.
