Routine health screening tests are one of the most effective ways to detect diseases early, when they are easiest to treat. Many serious conditions, including cancer, diabetes, and heart disease, develop silently for years before symptoms appear. A proactive approach to health screening can literally save your life.
The screenings you need depend primarily on your age, sex, family history, and personal risk factors. This guide organizes the most important health screenings by age group, based on recommendations from the U.S. Preventive Services Task Force (USPSTF), the American Cancer Society, the CDC, and other leading medical organizations.
Screenings for Adults in Their 20s
Even young, healthy adults should establish a baseline with certain health screenings. Blood pressure should be checked at least every two years if readings are normal (below 120/80 mmHg), or annually if you have elevated readings, according to the American Heart Association. High blood pressure affects approximately one in four adults aged 20 to 44, per CDC data.
Cholesterol screening (a lipid panel) should begin at age 20 for individuals with risk factors such as obesity, diabetes, smoking, or a family history of heart disease. For those without risk factors, the USPSTF recommends screening starting at age 35 for men and age 45 for women, though many clinicians recommend earlier baseline testing.
Additional screenings for adults in their 20s include STI screening (chlamydia and gonorrhea annually for sexually active women under 25, and HIV screening at least once for all adults), cervical cancer screening with a Pap smear starting at age 21 (every three years), skin checks for unusual moles or changes, and depression screening. Dental exams should occur every six months, and vision screening every two years or as recommended.
Screenings for Adults in Their 30s
In your 30s, many of the same screenings continue. Cervical cancer screening transitions to an option of HPV co-testing (Pap plus HPV test) every five years beginning at age 30, as recommended by the USPSTF. Blood pressure and cholesterol checks continue at the same intervals established in your 20s.
Diabetes screening with a fasting blood glucose or hemoglobin A1c test should begin at age 35 for adults who are overweight or obese, according to the USPSTF. If you have additional risk factors such as a family history of type 2 diabetes, a history of gestational diabetes, or polycystic ovary syndrome, screening may be recommended earlier.
Skin cancer awareness becomes more important in your 30s, particularly if you have a history of sun exposure, sunburns, or a family history of melanoma. While the USPSTF has not issued a definitive recommendation for routine skin cancer screening in the general population, the American Academy of Dermatology recommends regular self-exams and professional skin checks for individuals with risk factors.
Screenings for Adults in Their 40s
Your 40s bring several important new screening recommendations. Diabetes screening is recommended for all adults aged 35 to 70 who are overweight or obese, with repeat testing every three years if results are normal, per USPSTF guidelines. Blood pressure and cholesterol screening continue at regular intervals.
Mammography for breast cancer screening is a topic of evolving guidelines. The USPSTF updated its recommendation in 2024 to advise biennial mammography screening starting at age 40 for women of average risk, aligning with the American Cancer Society’s recommendation. Women with higher risk factors, including a family history of breast cancer or known genetic mutations (BRCA1/BRCA2), may need to begin screening earlier and at more frequent intervals, potentially including breast MRI.
Eye exams become more important in your 40s as presbyopia (age-related difficulty focusing on close objects) commonly develops. The American Academy of Ophthalmology recommends a comprehensive eye exam at age 40 as a baseline evaluation. Individuals with diabetes should have annual dilated eye exams to screen for diabetic retinopathy.
Screenings for Adults in Their 50s
The 50s are a critical decade for cancer screening. Colorectal cancer screening is recommended starting at age 45, per both the USPSTF and the American Cancer Society. Options include colonoscopy every 10 years, flexible sigmoidoscopy every five years, or stool-based tests such as FIT (fecal immunochemical test) annually or Cologuard every three years. Colonoscopy remains the gold standard because it allows both detection and removal of precancerous polyps during the same procedure.
Lung cancer screening with low-dose CT scan is recommended annually for adults aged 50 to 80 who have a 20 pack-year smoking history and currently smoke or have quit within the past 15 years, according to the USPSTF. This screening has been shown to reduce lung cancer mortality by approximately 20% in the National Lung Screening Trial.
Men should discuss prostate cancer screening with their doctor starting at age 55 (or earlier for Black men and those with a family history). The USPSTF recommends shared decision-making for PSA-based screening in men aged 55 to 69, weighing the potential benefits against risks such as false positives and overtreatment. Bone density screening (DEXA scan) for osteoporosis is recommended for women aged 65 and older, or earlier for those with risk factors.
Screenings for Adults 60 and Older
In your 60s and beyond, maintaining regular screenings is essential for catching age-related conditions early. Colorectal, breast, and lung cancer screenings continue according to the schedules established in earlier decades. Shingles vaccination (Shingrix) is recommended at age 50 or older, and pneumococcal vaccination is recommended at 65 or older, per CDC guidelines.
Abdominal aortic aneurysm screening with a one-time ultrasound is recommended for men aged 65 to 75 who have ever smoked, per the USPSTF. An abdominal aortic aneurysm is a potentially fatal condition that usually has no symptoms until the aorta ruptures. Hepatitis C screening is recommended as a one-time test for all adults aged 18 to 79, per the USPSTF.
Fall risk assessment, hearing tests, and cognitive screening become relevant in the late 60s and 70s. The USPSTF recommends exercise interventions to prevent falls in community-dwelling adults aged 65 and older. Annual wellness visits covered by Medicare include a review of your health risk factors, screening schedules, and advance care planning.
Screenings Based on Family History and Risk Factors
Standard screening guidelines are based on average-risk populations. If you have a family history of cancer, heart disease, diabetes, or other conditions, your doctor may recommend earlier or more frequent screenings. For example, individuals with a first-degree relative who had colorectal cancer should begin screening at age 40 or 10 years before the relative’s age at diagnosis, whichever is earlier.
Genetic testing and counseling may be recommended if you have a strong family history of hereditary cancer syndromes (such as BRCA mutations for breast and ovarian cancer, or Lynch syndrome for colorectal cancer). These tests can inform personalized screening and prevention strategies.
Lifestyle factors also influence screening recommendations. If you smoke, have obesity, are sedentary, or have a history of heavy alcohol use, discuss additional screenings with your healthcare provider. Occupational exposures to chemicals, radiation, or other hazards may also warrant specific screening tests.
Making the Most of Preventive Care
Under the ACA, most preventive screenings recommended by the USPSTF with an A or B grade are covered at no out-of-pocket cost by all Marketplace and employer plans. This includes blood pressure checks, cholesterol screening, diabetes screening, colorectal cancer screening, breast cancer screening, cervical cancer screening, and many others. Medicare also covers a wide range of preventive services at no cost.
Keep a personal health record that tracks your screening history, results, and upcoming due dates. Many healthcare systems offer patient portals where you can access this information electronically. Discuss your complete family history with your doctor so they can tailor screening recommendations to your individual risk profile. For more health and wellness information, visit our wellness guide.
Frequently Asked Questions
Are health screenings covered by insurance?
Yes. Under the ACA, most recommended preventive screenings are covered at 100% with no copay, deductible, or coinsurance when performed by an in-network provider. This applies to Marketplace plans, employer plans, and Medicare. Verify coverage with your insurer before scheduling to confirm which tests are included.
What is the difference between a screening and a diagnostic test?
A screening test is performed on individuals without symptoms to detect disease early. A diagnostic test is performed when symptoms are present or when a screening test returns an abnormal result. Insurance may cover screenings at no cost under preventive care benefits, while diagnostic tests are subject to normal cost-sharing.
How often should I get a general health checkup?
Most adults benefit from an annual wellness visit with their primary care provider, during which screening tests, vaccinations, and health concerns can be addressed. The frequency of specific tests varies by age and risk factors. Your doctor can create a personalized screening schedule based on your individual health profile.
Can I skip screenings if I feel healthy?
Many serious conditions, including high blood pressure, high cholesterol, diabetes, and early-stage cancers, cause no symptoms in their early stages. Screening tests are specifically designed to catch these conditions before symptoms develop, when treatment is most effective. Skipping screenings because you feel healthy defeats the purpose of preventive care.
Stay Ahead of Your Health
Health screening is a proactive investment in your well-being. Follow the evidence-based guidelines for your age and risk factors, take advantage of the preventive care benefits included in your insurance plan, and partner with your primary care provider to stay on schedule. Detecting a condition early through routine screening can make the difference between a simple treatment and a life-threatening diagnosis.
