Cancer screening means checking for cancer before you feel sick. Early detection can save lives by catching cancer at a stage when treatment is more effective. The right tests for you depend mostly on your age, your sex, and your health history. A test that helps a 60-year-old may not help a 30-year-old at all. This guide offers clear, decade-by-decade recommendations for cancer screening for people at average risk. That means no personal history of cancer, no strong family history, and no special health problems.

Understanding Cancer Screening and Risk
Cancer screening aims to find cancer early, before symptoms appear. Early detection often leads to better outcomes. However, not everyone needs the same tests or at the same time. Screening recommendations vary by:
Age
Sex
Personal and family health history
This guide focuses on people at average risk. If you have a family history of cancer or other risk factors, talk to your healthcare provider about personalized screening plans.
Screening in Your 20s and 30s
For most people in their 20s and 30s, cancer screening focuses on cancers that can develop early or are common in younger adults.
Cervical Cancer Screening (Women)
Start Pap tests at age 21.
Pap tests check for precancerous changes in cervical cells.
Between ages 21 and 29, get a Pap test every 3 years.
From age 30 to 65, Pap tests combined with HPV testing every 5 years is preferred.
Skin Cancer Awareness
Check your skin regularly for new or changing moles or spots.
See a dermatologist if you notice anything unusual.
Protect your skin from excessive sun exposure to reduce risk.
Testicular Cancer Awareness (Men)
Testicular cancer is rare but most common in younger men.
Perform monthly self-exams to check for lumps or changes.
Report any abnormalities to your doctor promptly.
Screening in Your 40s
Cancer risk begins to rise in your 40s. Screening focuses on cancers that become more common at this age.
Breast Cancer Screening (Women)
Begin discussing mammograms with your healthcare provider at age 40.
Mammograms can detect breast cancer early.
The decision to start screening at 40 depends on personal risk factors.
If no risk factors, screening every 1-2 years is common.
Colorectal Cancer Screening
Begin colorectal cancer screening at age 45 for average-risk adults.
Options include colonoscopy every 10 years, stool tests annually, or other methods.
Early detection of polyps can prevent cancer.
Skin Cancer Checks
Continue regular skin self-exams.
Consider professional skin exams if you have risk factors like fair skin or history of sunburns.
Screening in Your 50s
Cancer screening becomes more important in your 50s as risk increases.
Breast Cancer Screening (Women)
Mammograms every year or two are recommended from age 50 to 74.
Continue regular clinical breast exams.
Colorectal Cancer Screening
Continue regular colorectal screening as recommended.
Colonoscopy every 10 years remains a common choice.
Lung Cancer Screening
For adults aged 50 to 80 with a history of heavy smoking (30 pack-years or more), annual low-dose CT scans are recommended.
Talk to your doctor if you qualify.
Prostate Cancer Screening (Men)
Discuss prostate cancer screening with your doctor starting at age 50.
Screening includes PSA blood test and possibly a digital rectal exam.
Decisions should be based on personal risk and preferences.
Screening in Your 60s and Beyond
Screening remains important but may change based on overall health and life expectancy.
Breast Cancer Screening (Women)
Continue mammograms every 1-2 years up to age 74.
After 75, screening decisions depend on health status.
Colorectal Cancer Screening
Continue screening until age 75.
After 75, discuss with your doctor whether to continue based on health.
Lung Cancer Screening
Continue annual low-dose CT scans if you meet criteria and are in good health.
Other Screenings
Skin cancer checks remain important.
Discuss any new symptoms or concerns with your healthcare provider promptly.
Special Considerations
Some people need to start screening earlier or have more frequent tests. This includes those with:
Family history of cancer
Genetic conditions
Previous cancer diagnosis
Other health problems
Always share your full health history with your doctor to get the best screening plan.
How to Prepare for Screening
Know your family health history.
Keep track of your screening dates and results.
Ask your healthcare provider about the benefits and risks of each test.
Stay informed about new screening guidelines.
