Your 20s

Ages 19-29

A time of reproductive health awareness, cancer prevention through screening, and establishing lifelong health habits.

Key Milestone

Cervical cancer screening begins at age 21 — regardless of when you became sexually active. Before age 21, the risk of cervical cancer is very low and screening can lead to unnecessary procedures.

Recommended Screenings

Cervical Cancer Screening

Starts at 21

When:Every 3 years, starting at age 21

What:Pap test (cytology) alone. HPV co-testing is an option starting at age 25.

Why:Detects precancerous changes early when they're most treatable

Note: Even if you've had the HPV vaccine, you still need regular Pap tests.
