Each year 1.2 million women have abnormal Pap tests, which show the distorted cells, or dysplasia.

These distorted cells, which can be detected in Pap tests, frequently evolve into a serious cancer if left untreated.

These distorted cells block small blood vessels and cause vascular inflammation, leading to organ damage, stroke and other problems.

Cigarette smoking has emerged as a powerful influence in the development of cervical cancer as well as distorted cells that are precursors of malignancy, researchers say.
