Cervical Cancer screening (Pap smear)
This is largely for women aged 21 to 65, and it should basically be done every three years. Doctors, however, recommend that if you are 30 or older, you can have the test every five years if you combine it with a screen for HPV, which is a sexually transmitted disease (STD) that can lead to cervical cancer. The pap smear would test for the presence of precancerous or cancerous cells on the cervix.
