Between ages 65 to 70 you can stop having Pap Smears done.
You can still continue to have Pap Smears done after age 70 if you want too but if your previous Pap Smears were coming back as negative then your risk of Cervical Cancer after age 65 to 70 years of age is very small.
Women should begin Pap Smears at age 21 and continue to have those Pap Smears done until at least age 65.
