Cancer Screening by Age
A quick reference for adults at average risk
In your 20s and 30s
- Cervical cancer: screening (Pap and/or HPV test) generally starts in the mid-20s and repeats every 3–5 years.
- HPV vaccine: catch-up vaccination is recommended through age 26 if not fully vaccinated.
- Know your body: report new lumps, skin changes, or unusual symptoms to a doctor.
In your 40s
- Breast cancer: mammograms every 1–2 years are recommended starting at 40 for women at average risk.
- Colorectal cancer: screening starts at 45 — options include at-home stool tests or colonoscopy.
- Cervical cancer: continue on your regular schedule.
In your 50s, 60s, and beyond
- Continue breast (to about 74) and colorectal (to about 75) screening on schedule.
- Lung cancer: ages 50–80 with a 20 pack-year smoking history — ask about yearly low-dose CT screening.
- Prostate cancer: men 55–69 should discuss the pros and cons of PSA testing with their doctor.
- Cervical cancer: many women can stop after 65 with a history of normal results — confirm with your doctor first.
At any age
- A strong family history of cancer can mean starting screening earlier — tell your doctor.
- All adults 18–79 should get a one-time hepatitis C test.
These are general guidelines for average risk. Your doctor tailors the plan to your health and family history.
