Inflammation merely means the cervix is irritated for some reason. In the absence of any symptoms or any other significant abnormality on the Pap, it can be safely ignored.
If inflammation is severe enough, it may interfere with the ability of the cytologist to accurately read the Pap. In such cases, it is wise to repeat the Pap at more frequent intervals (6-9 months) rather than the usual once a year.
Inflammation by itself need not be treated. If other abnormalities are identified in addition to the inflammation, you may treat the other problems and the inflammation will probably go away.
