Don’t screen with Pap smears if under 25 years of age or over 69 years of age.

-Don’t do screening Pap smears annually in those with previously normal results
-Don’t do Pap smears in those who have had a hysterectomy for non-malignant disease.

The potential harm from screening younger than 25 years of age outweighs the benefits and there is little evidence to suggest the necessity of conducting this test annually when previous test results were normal. Those who have had a full hysterectomy for benign disorders no longer require this screening. Screening should stop at age 70 if three previous test results were normal.
