Health issues and infections can cause changes in the cells of the cervix. These changes are called cervical dysplasia. Some of these changes can lead to cancer. A pap test can find these changes early and stop cancer from developing. The test can also detect cancer cells that have already developed.
A pap test is a recommended part of regular cancer screening. There are many different guidelines on how often the test should be done. The doctor and patient will decide what schedule is best. Some general guidelines include:

The pelvic exam takes less than 5 minutes.
A Pap test is generally painless. You may feel some pressure or a small cramp when the cervix is wiped to gather cells.
