Arrange a prompt visit sooner for unexplained bleeding, unusual discharge, or pelvic pain.
Follow-up is essential even after abnormal tissue has been removed.
Treatment greatly reduces risk, but it does not guarantee that HPV has cleared or that abnormal cells will never return.
If the early follow-up tests are reassuring, testing can become less frequent.
Current U.S. risk-based guidance recommends long-term surveillance at three-year intervals for at least 25 years after treatment of high-grade disease, after the initial series of negative follow-up tests.
Surveillance may continue beyond age 65 when health status allows.
Routine follow-up is appropriate when there are no new symptoms and a monitoring plan is already in place.
People who become pregnant, start immune-suppressing treatment, or receive a new HIV diagnosis should tell the clinician managing their cervical follow-up because the plan may need to change.

People being observed rather than treated also need testing and, in some cases, repeat colposcopy at the recommended times.
Missing these visits can allow persistent high-grade changes to go unnoticed.
