Cancer Screening by Age (2025): Simple Guide

---

🧭 What this guide is (and isn’t)

This is a plain-English map of cancer screening for average-risk people. It aligns with major guidelines (USPSTF baseline; ACS and CDC where helpful). Always tailor with your clinician if you’re higher-risk (e.g., strong family history, known genetic syndrome like BRCA1/2, prior cancer, chest radiation in youth, or symptoms). uspreventiveservicestaskforce.org+1Cancer.org

Inclusive wording. We say “people with a cervix,” “people with breasts,” and “people with a prostate,” because bodies differ. Follow the test for the organ you have.

✅ Quick Start: Do this today

1. Find your age band in the checklist below and list the matching tests.

2. Book what’s due (or overdue) in the next 90 days.

3. Pick your colorectal option (FIT stool test yearly or colonoscopy every 10 years, others in between). uspreventiveservicestaskforce.org

4. If you ever smoked, check if you qualify for annual low-dose CT for lung cancer. uspreventiveservicestaskforce.org

5. If you’re 40+, schedule regular mammograms. uspreventiveservicestaskforce.org

6. Bring your family history; ask if you need genetic counseling/testing (e.g., BRCA). uspreventiveservicestaskforce.org

7. Set yearly reminders with MyHealthfinder/Prevention TaskForce (links in Tools). odphp.health.govuspreventiveservicestaskforce.org

📊 Age-by-Age Screening Checklist (2025)

Scope: For people without symptoms and at average risk. Intervals shown are for ongoing screening while you remain eligible. Stopping rules vary—review at each visit.

Ages 0–20

• Routine cancer screening not recommended for asymptomatic, average-risk children/teens.

• HPV vaccination prevents future HPV-related cancers (not a screen). Start at 11–12 years (as early as 9); catch-up through 26; 27–45 by shared decision-making. CDC+1

Ages 21–29

• Cervical (people with a cervix): Pap (cytology) every 3 years. No HPV testing yet for average-risk per USPSTF. uspreventiveservicestaskforce.org

• Not recommended: Routine testicular, thyroid, ovarian, pancreatic screening. uspreventiveservicestaskforce.org+3uspreventiveservicestaskforce.org+3uspreventiveservicestaskforce.org+3

Ages 30–39

• Cervical (people with a cervix, 30–65): Choose one: primary hrHPV every 5 years, or Pap every 3 years, or co-test (Pap+hrHPV) every 5 years. (Self-collected HPV is emerging in some settings—watch for availability.) uspreventiveservicestaskforce.org+1

• Breast (people with breasts): Discuss starting in 40s; routine begins at 40 (next band). uspreventiveservicestaskforce.org

Ages 40–44

• Breast: Begin biennial mammography at 40 and continue through 74. uspreventiveservicestaskforce.org

• Cervical: Continue schedule above. uspreventiveservicestaskforce.org

Ages 45–49

• Colorectal (all adults): Start screening at 45. Options:

  • FIT (stool) every year

  • Stool DNA-FIT every 1–3 years

  • CT colonography every 5 years

  • Flexible sigmoidoscopy every 5 years (or every 10 with annual FIT)

  • Colonoscopy every 10 years
    Choose the test you’ll actually complete. uspreventiveservicestaskforce.org

• Breast/Cervical: Continue. uspreventiveservicestaskforce.org+1

Ages 50–59

• Lung (high-risk only): Annual low-dose CT if 50–80, ≥20 pack-years, and smoke now or quit within 15 years. (A pack-year ≈ 20 cigarettes/day × 1 year.) Stop if >15 years since quitting or if you can’t undergo curative treatment. uspreventiveservicestaskforce.org

• Prostate (people with a prostate, 55–69): Shared decision-making about PSA screening; some will opt in, others won’t. Not routinely before 55. uspreventiveservicestaskforce.org

• Breast/Colorectal/Cervical: Continue. uspreventiveservicestaskforce.org+2uspreventiveservicestaskforce.org+2

Ages 60–64

• Continue breast, colorectal, cervical (if still 60–65), and lung (if eligible). uspreventiveservicestaskforce.org+2uspreventiveservicestaskforce.org+2

Ages 65–74

• Cervical: Many can stop at 65 if there’s adequate prior negative screening and no high-risk history—confirm with your clinician. uspreventiveservicestaskforce.org

• Breast: Continue biennial mammograms through 74. Evidence is insufficient for 75+. uspreventiveservicestaskforce.org

• Colorectal: Strongly recommended through 75; 76–85 is individualized based on health and prior tests. uspreventiveservicestaskforce.org

• Lung: Continue annually if eligible until 80. uspreventiveservicestaskforce.org

• AAA (men who have ever smoked, 65–75): One-time ultrasound. (Selective for men who never smoked; not for women who never smoked and lack risk factors.) uspreventiveservicestaskforce.org

• Osteoporosis (women 65+; younger postmenopausal at risk): DXA bone density test. uspreventiveservicestaskforce.org

Ages 75+

• Breast: Evidence insufficient ≥75—decide individually. uspreventiveservicestaskforce.org

• Colorectal: Ages 76–85—case-by-case; >85—generally stop. uspreventiveservicestaskforce.org

• Prostate: Do not screen routinely at ≥70. uspreventiveservicestaskforce.org

• Lung: Stop at 80 or sooner if >15 years since quitting or if unable to undergo treatment. uspreventiveservicestaskforce.org

Not recommended for average-risk, asymptomatic adults: routine screening for ovarian, pancreatic, thyroid, testicular, and skin (insufficient for clinician exam). Lifestyle risk reduction and symptom awareness still matter. uspreventiveservicestaskforce.org+4uspreventiveservicestaskforce.org+4uspreventiveservicestaskforce.org+4

🧠 Techniques & Frameworks to stay on track

The S.C.R.E.E.N. method

• Schedule your annual “prevention month.”

• Choose tests you’ll complete (e.g., FIT vs colonoscopy). uspreventiveservicestaskforce.org

• Risk-check family history and smoking history. uspreventiveservicestaskforce.org+1

• Evidence-based intervals—don’t under- or over-screen. uspreventiveservicestaskforce.org+1

• Eligibility reassess yearly (e.g., turning 45, quitting smoking 15 years ago). uspreventiveservicestaskforce.org+1

• Next reminder—set it before you leave the clinic (apps in Tools). uspreventiveservicestaskforce.org

🛠️ Quick Start (step-by-step)

1. Open MyHealthfinder and print your personalized list. odphp.health.gov

2. Call one imaging center + one primary care office; ask for “screening mammogram,” “FIT kit,” or “colonoscopy scheduling,” and (if eligible) “low-dose CT.” uspreventiveservicestaskforce.org+2uspreventiveservicestaskforce.org+2

3. Set calendar holds (prep, test day, results call).

4. Create a small reward (nice coffee, movie night) for completing your tests—habits stick when they feel good.

👥 Audience variations

• Students/young adults (21–29): Stay on top of cervical screening; complete HPV vaccination if not done. uspreventiveservicestaskforce.orgCDC

• Parents in their 30s–40s: Mammograms start at 40; colorectal at 45—book both in one planning burst. uspreventiveservicestaskforce.org+1

• Busy professionals (50–60s): Eligible for lung CT? Many don’t realize they qualify at 50 with 20 pack-years; add it to annual planning. uspreventiveservicestaskforce.org

• Seniors (65+): Revisit “when to stop” with your clinician; add bone density if due; one-time AAA ultrasound may apply. uspreventiveservicestaskforce.org+1

⚠️ Mistakes & myths to avoid

• “Colonoscopy is the only option.” Not true. FIT yearly, stool DNA-FIT q1–3y, CT colonography q5y, sigmoidoscopy options exist. Choose what you’ll complete. uspreventiveservicestaskforce.org

• “PSA is always good.” PSA screening has trade-offs; ages 55–69 decide with your clinician; avoid routine screening ≥70. uspreventiveservicestaskforce.org

• “A normal mammogram means I can wait 3–4 years.” USPSTF recommends every other year from 40 to 74. uspreventiveservicestaskforce.org

• “Everyone needs a skin cancer check yearly.” Evidence is insufficient for routine clinician visual skin exams in asymptomatic adults. uspreventiveservicestaskforce.org

• “Pap smears start with sex or at 18.” For average risk, start at 21. uspreventiveservicestaskforce.org

💬 Real-life examples & scripts

• Booking colorectal (FIT):
  “Hi, I’m 46 and due for colorectal screening. I prefer a FIT kit mailed or pick-up, please. Can we confirm insurance coverage and where to drop the sample?” uspreventiveservicestaskforce.org

• Shared decision for PSA (55–69):
  “I’m 60 with no urinary symptoms. Can we discuss PSA screening—benefits vs harms, and how often if I choose it?” uspreventiveservicestaskforce.org

• Lung screening check:
  “I’m 55, smoked ~25 pack-years, quit 10 years ago. Do I qualify for annual low-dose CT?” uspreventiveservicestaskforce.org

• Stopping cervical at 65:
  “I’ve had consistent negative tests. Am I safe to stop cervical screening now?” uspreventiveservicestaskforce.org

❓ FAQs

1) I’m average-risk and 45. Is FIT “good enough,” or do I need a colonoscopy?
FIT yearly is an endorsed option; colonoscopy every 10 years is another. The best test is the one you’ll complete on schedule. uspreventiveservicestaskforce.org

2) I have dense breasts. Do I need extra screening?
USPSTF calls for more research on added tests for dense breasts; discuss local practice with your clinician and consider your personal risk. uspreventiveservicestaskforce.org

3) Can I self-collect for cervical (HPV) screening?
Primary hrHPV every 5 years is acceptable 30–65; self-collection pathways are emerging where approved—ask your clinic about availability. uspreventiveservicestaskforce.org+1

4) When can I stop cervical cancer screening?
At 65, many can stop after adequate prior negative tests and no high-risk history—confirm individually. uspreventiveservicestaskforce.org

5) Do I still qualify for lung screening if I quit 16 years ago?
No. Eligibility is 50–80 with ≥20 pack-years, currently smoking or quit within 15 years. uspreventiveservicestaskforce.org

6) Should all men get PSA tests every year?
No. Ages 55–69: decide together with your clinician; ≥70: do not screen routinely. uspreventiveservicestaskforce.org

7) Is a yearly skin exam recommended for everyone?
Evidence is insufficient to recommend for or against routine clinician skin exams for asymptomatic adults. Practice varies—ask your clinician. uspreventiveservicestaskforce.org

8) I’m 67 and healthy—should I keep doing colonoscopies?
Probably continue some form of screening until 75, then individualize 76–85 based on health, prior findings, and preferences. uspreventiveservicestaskforce.org

9) Are there screens for ovarian or pancreatic cancer for healthy people?
No—routine screening isn’t recommended for average-risk, asymptomatic adults; focus on symptom awareness and risk reduction. uspreventiveservicestaskforce.org+1

10) What about bone health and aneurysm checks—are those “cancer screens”?
Not cancer screens, but important at older ages: DXA for osteoporosis (women 65+) and one-time AAA ultrasound for men 65–75 who ever smoked. uspreventiveservicestaskforce.org+1
