Health Screening Tests by Age: What You Need and When

Routine health screening tests are one of the most effective ways to detect disease early, when it is easiest to treat. Many serious conditions — including cancer, diabetes, and heart disease — can develop silently for years before symptoms appear. A proactive approach to health screening, guided by your doctor, is one of the best investments you can make in your long-term health.

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. Guidelines are updated periodically and can differ between organizations, so treat the specifics below as a starting point and confirm what is right for you with your clinician. This article is general education, not medical advice.

Screenings for Adults in Their 20s

Even young, healthy adults benefit from establishing a baseline. Blood pressure should generally be checked at least every two years if readings are normal (below 120/80 mmHg), or more often if readings are elevated, consistent with American Heart Association guidance. High blood pressure is common even among younger adults and usually causes no symptoms, which is exactly why screening matters.

Cholesterol screening (a lipid panel) is often started earlier for people with risk factors such as obesity, diabetes, smoking, or a family history of early heart disease. For average-risk adults, guidelines on the exact starting age vary, and many clinicians recommend a baseline in your 20s or 30s; your doctor can advise based on your risk. Additional screenings in your 20s commonly include STI screening (for example, chlamydia and gonorrhea for sexually active younger women, and HIV screening at least once for adults and adolescents), cervical cancer screening starting at age 21, skin checks for changing moles, and depression screening. Routine dental and vision care rounds out preventive visits.

Screenings for Adults in Their 30s

In your 30s, many of the same screenings continue. Cervical cancer screening for average-risk people ages 30 to 65 has historically offered options such as a Pap test every three years, an HPV test every five years, or co-testing every five years. Guidance in this area has been evolving — including toward primary HPV testing and self-collection options in some settings — so ask your clinician which current option is recommended for you. Blood pressure and cholesterol checks continue at intervals set by your readings and risk.

Diabetes screening (fasting glucose or hemoglobin A1c) is generally recommended for adults who are overweight or obese beginning in this age range, per the USPSTF, and earlier if you have added risk factors such as a family history of type 2 diabetes, a history of gestational diabetes, or polycystic ovary syndrome. Skin cancer awareness also grows in importance, especially with a history of sun exposure or a family history of melanoma. While routine skin cancer screening of the general population is not universally recommended, regular self-exams and professional checks are commonly advised for higher-risk individuals.

Screenings for Adults in Their 40s

Your 40s bring several important additions. Diabetes screening is recommended for adults in the roughly 35-to-70 age range who are overweight or obese, with repeat testing periodically if results are normal, per USPSTF guidance. Blood pressure and cholesterol screening continue.

Mammography for breast cancer is a key milestone. The USPSTF recommends biennial (every other year) mammography starting at age 40 for women of average risk, which aligns with several other organizations. Women with higher risk — such as a strong family history or known genetic mutations like BRCA1/BRCA2 — may need to begin earlier and screen more often, sometimes including breast MRI; discuss your personal risk with your doctor.

Eye health also becomes more relevant as presbyopia (age-related difficulty focusing up close) develops. A baseline comprehensive eye exam around age 40 is commonly recommended, and people with diabetes should have regular 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 generally recommended starting at age 45, per both the USPSTF and the American Cancer Society. Options include colonoscopy every 10 years, flexible sigmoidoscopy, or stool-based tests such as a fecal immunochemical test (FIT) annually or a stool DNA test every one to three years. Colonoscopy is often described as the reference standard because it can both detect and remove precancerous polyps in one procedure, but the best test is frequently the one you will actually complete — talk with your doctor about which fits you.

Lung cancer screening with low-dose CT is recommended annually for adults roughly ages 50 to 80 who have a significant smoking history (about a 20 pack-year history) and currently smoke or quit within the past 15 years, per the USPSTF. Men may begin discussing prostate cancer screening with their doctor; the USPSTF recommends shared, individualized decision-making about PSA testing for men roughly 55 to 69, weighing benefits against risks like false positives and overtreatment, with earlier discussion often appropriate for Black men and those with a family history. Bone density (DEXA) screening for osteoporosis is recommended for women 65 and older, or earlier for those at increased risk.

Screenings for Adults 60 and Older

In your 60s and beyond, staying current on screenings helps catch age-related conditions early. Colorectal, breast, and lung cancer screenings continue on their established schedules within recommended age ranges. On immunizations, the CDC generally recommends shingles vaccination (Shingrix) for adults 50 and older and pneumococcal vaccination for older adults, along with annual influenza vaccination and staying up to date on COVID-19 and other recommended vaccines — check the current CDC adult schedule with your clinician.

Abdominal aortic aneurysm screening with a one-time ultrasound is recommended for men ages 65 to 75 who have ever smoked, per the USPSTF; an aneurysm often causes no symptoms until it ruptures. Hepatitis C screening is recommended at least once for adults ages 18 to 79. Fall-risk assessment, hearing tests, and cognitive check-ins also become relevant in the late 60s and 70s. Medicare’s annual wellness visit includes a review of your risk factors, screening schedule, and advance care planning.

Screenings Based on Family History and Risk Factors

Standard guidelines are built around 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 screening. For example, people with a first-degree relative who had colorectal cancer are often advised to begin screening earlier than the general population — commonly around age 40, or 10 years before the relative’s age at diagnosis, whichever is earlier.

Genetic testing and counseling may be recommended for a strong family history of hereditary cancer syndromes (such as BRCA-related breast and ovarian cancer, or Lynch syndrome for colorectal cancer). These can inform personalized screening and prevention plans. Lifestyle factors matter too: if you smoke, have obesity, are sedentary, or drink heavily, discuss additional screenings with your provider. Occupational exposures to chemicals or radiation may also warrant specific tests.

Making the Most of Preventive Care

Under the ACA, most preventive services that carry an A or B grade from the USPSTF — along with recommended immunizations and certain women’s and children’s preventive services — are generally covered with no out-of-pocket cost when delivered in-network by non-grandfathered Marketplace and employer plans. This commonly includes blood pressure checks, cholesterol and diabetes screening, and colorectal, breast, and cervical cancer screening. Medicare also covers many preventive services at no cost. Coverage rules can change, so verify with your insurer before scheduling and confirm whether a specific test is billed as screening or diagnostic.

Keep a personal health record that tracks your screening history, results, and upcoming due dates; many health systems offer patient portals for this. Share your complete family history with your doctor so recommendations can be tailored to you. For more health and wellness information, visit our wellness guide.

Frequently Asked Questions

Are health screenings covered by insurance?

Often, yes. Under the ACA, most recommended preventive screenings are covered at no cost sharing when performed in-network under a non-grandfathered plan, and this applies to many Marketplace plans, employer plans, and Medicare. Rules and lists can change, so verify coverage with your insurer before scheduling to confirm which tests are included and how they will be billed.

What is the difference between a screening and a diagnostic test?

A screening test is performed on someone without symptoms to detect disease early. A diagnostic test is performed when symptoms are present or when a screening result is abnormal. Screenings are often covered at no cost under preventive-care benefits, while diagnostic tests are typically subject to normal cost sharing.

How often should I get a general health checkup?

Many adults benefit from a periodic wellness visit with a primary care provider, where screenings, vaccinations, and concerns can be addressed. The frequency of specific tests varies by age and risk, and your doctor can build a personalized schedule for you.

Can I skip screenings if I feel healthy?

Feeling well does not mean you are in the clear. High blood pressure, high cholesterol, diabetes, and early-stage cancers often cause no symptoms at first. Screening tests are designed to catch these conditions before symptoms appear, when treatment tends to work best.

Do screening guidelines ever change?

Yes. Organizations such as the USPSTF, CDC, and American Cancer Society update recommendations as new evidence emerges, and they do not always agree on every detail. That is why this guide points you to current sources and, most importantly, to your own clinician, who can weigh your individual risk.

Stay Ahead of Your Health

Health screening is a proactive investment in your well-being. Follow the evidence-based guidance for your age and risk factors, take advantage of the preventive-care benefits in your insurance plan, and partner with your primary care provider to stay on schedule and up to date as recommendations evolve. Detecting a condition early through routine screening can be the difference between a simple treatment and a far more serious diagnosis. When in doubt about what applies to you, ask your doctor.
