Many serious health conditions, such as high blood pressure, diabetes, high cholesterol and some cancers, develop quietly and cause few symptoms at first. Screening tests are designed to find problems early, when they are often easier to treat. Which tests you need depends on your age, sex, family history, lifestyle and personal risks. This guide offers a general overview. Recommendations differ between countries and organizations, so always confirm what is right for you with your doctor.
Why Screenings Matter
- They can detect conditions before symptoms appear.
- Early treatment often leads to better outcomes.
- They help you understand your personal risks and take preventive action.
In Your 20s and 30s
- Blood pressure: at least every 2 years if normal, more often if elevated.
- Cholesterol: a baseline test in early adulthood, and sooner with risk factors or family history.
- Cervical screening: for people with a cervix, regular Pap or HPV testing as advised locally.
- Sexual health: testing for sexually transmitted infections if you are at risk.
- Skin, dental and eye checks: regular dental exams and eye tests, plus skin checks if you notice changes.
- Mental health: mention mood, anxiety or sleep problems at checkups.
In Your 40s
- Blood pressure and cholesterol: regular checks, usually every 1 to 2 years.
- Diabetes screening: a blood sugar or HbA1c test, especially if you are overweight or have risk factors. Many guidelines suggest starting around age 35 to 45.
- Breast cancer screening: mammograms are often recommended from around age 40 to 50, depending on local guidelines and risk.
- Eye exam: every 1 to 2 years, since vision changes become common.
In Your 50s
- Colorectal cancer screening: many guidelines recommend starting at 45 to 50, using colonoscopy or stool-based tests.
- Lung cancer screening: low-dose CT may be recommended for older adults with a significant smoking history.
- Prostate health: men should discuss the pros and cons of PSA testing with their doctor.
- Bone health: discuss bone density testing, especially after menopause.
In Your 60s and Beyond
- Continue blood pressure, cholesterol, diabetes and cancer screenings as advised.
- Bone density testing, particularly for women over 65.
- Hearing, vision and fall-risk assessments.
- Memory and cognitive checks if you or your family have concerns.
- Review of medications and vaccinations, such as flu, pneumonia and shingles.
