The short explanation
HSIL means high-grade squamous intraepithelial lesion. It tells you the lab saw cells with more marked changes, which have a higher chance of progressing to cancer over time if they are not treated. It is a serious finding to act on, but it is not a cancer diagnosis. The aim of screening is to find exactly this stage, when treatment is usually effective. A colposcopy with biopsy is the standard next step. The biopsy shows how deep and how severe the changes are, which decides whether treatment is needed and what kind.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- If the biopsy confirms high-grade changes, common treatments remove or destroy the affected area of the cervix, often as a day procedure.
- Her age, menopausal status and any previous results will shape the plan. After menopause, the area of change can be harder to see, and the doctor may adjust the approach.
- You can go with her, help her write down questions, and ask for a woman clinician if she prefers.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot say what her biopsy will show or whether any cancer is present. Only the biopsy result can answer that.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- What exactly will the biopsy show, and when will results come?
- If treatment is needed, what are the options and recovery?
- Can treatment be done here, or will she be referred?
- How often will she need checks afterwards?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Emergency — call 112 now
- Call 112 or go to the nearest emergency department if you have very heavy vaginal bleeding, soaking through pads quickly, or bleeding with fainting, severe pain or breathlessness.
Book an appointment soon
- Help her keep the biopsy appointment, and see a clinician within a few days if she develops new bleeding, discharge or pelvic pain.
Raise it at a routine appointment
- After results, book the follow-up visit and note all future check dates.
