You feel fine, so do you really need health screenings?
For many adults, the answer is yes. Preventive screenings are designed to identify certain health problems before they cause noticeable symptoms. They can help detect conditions such as high blood pressure, diabetes, osteoporosis, and some cancers at an earlier stage, when there may be more options for treatment or prevention.
However, not every adult needs every screening every year. The right schedule depends on factors such as your age, sex, medical history, family history, lifestyle, medications, and individual risk factors.
Quick answer: Most adults need some form of preventive screening, but the specific tests and timing vary from person to person. Common screenings may include blood pressure, cholesterol, diabetes, certain cancer screenings, mental health screening, and bone-health assessment. Your primary care provider can help determine which screenings are appropriate for you.
Why Are Preventive Health Screenings Important?
Some serious health conditions develop gradually and may not cause obvious symptoms in their early stages.
For example, high blood pressure is often called a “silent” condition because many people do not feel unwell even when their readings are elevated.
Preventive screening can help:
- Identify health risks before symptoms develop
- Detect certain conditions earlier
- Monitor changes in your health over time
- Guide lifestyle or medication decisions
- Determine whether additional testing is needed
- Support long-term preventive care
The U.S. Preventive Services Task Force publishes evidence-based recommendations for many preventive health services.
Does Everyone Need the Same Health Screenings?
No. Screening recommendations are not one-size-fits-all.
Your healthcare provider may consider:
- Your age
- Your sex and reproductive history
- Your personal medical history
- Your family medical history
- Your weight and blood pressure
- Your smoking history
- Your medications
- Your occupation and lifestyle
- Your previous screening results
- Your individual risk factors
This is one reason regular annual wellness visits can be useful. They give you and your provider an opportunity to review which screenings are due and which may not be necessary yet.
1. Blood Pressure Screening
High blood pressure can increase the risk of heart disease, stroke, kidney disease, and other health problems.
The U.S. Preventive Services Task Force recommends screening adults aged 18 and older for high blood pressure.
If an elevated reading is found in a clinic, your provider may recommend measurements outside the medical office before diagnosing hypertension.
This may involve:
- Home blood pressure monitoring
- Ambulatory blood pressure monitoring
- Repeat clinic measurements
If you have noticed that your readings remain elevated, read our guide on why your blood pressure may stay high.
2. Cholesterol Screening
Cholesterol levels can help your provider estimate your risk of cardiovascular disease.
A lipid panel may measure:
- Total cholesterol
- LDL cholesterol
- HDL cholesterol
- Triglycerides
How often cholesterol should be checked depends on your age, previous results, cardiovascular risk, family history, medications, and other health conditions.
People with high blood pressure, diabetes, obesity, smoking history, or a strong family history of heart disease may need closer monitoring.
3. Prediabetes and Type 2 Diabetes Screening
Type 2 diabetes can develop gradually, and some people may have elevated blood sugar for years before noticing obvious symptoms.
The U.S. Preventive Services Task Force recommends screening for prediabetes and type 2 diabetes in adults aged 35 to 70 who have overweight or obesity.
Depending on your circumstances, screening may involve:
- Hemoglobin A1C
- Fasting blood glucose
- Oral glucose tolerance testing
Your provider may recommend screening outside this age range if you have additional risk factors.
Symptoms such as persistent thirst, frequent urination, or persistent hunger should also be discussed with your healthcare provider rather than waiting for a routine screening appointment.
4. Colorectal Cancer Screening
Colorectal cancer screening can identify cancer or precancerous changes before symptoms appear.
For adults at average risk, the U.S. Preventive Services Task Force recommends colorectal cancer screening beginning at age 45 and continuing through age 75.
Several screening options are available, including:
- Stool-based tests
- Colonoscopy
- CT colonography
- Other approved screening strategies
The frequency depends on which test is used.
People with a personal or strong family history of colorectal cancer, polyps, inflammatory bowel disease, or certain inherited conditions may need a different screening schedule.
5. Breast Cancer Screening
For women at average risk, the U.S. Preventive Services Task Force currently recommends mammography every two years from age 40 through age 74.
The appropriate approach may differ for people with:
- A previous breast cancer diagnosis
- A known high-risk genetic mutation
- A strong family history
- Previous high-dose chest radiation
- Other high-risk findings
If you are unsure when you should begin mammograms or how often you need them, discuss your individual risk with your healthcare provider.
6. Cervical Cancer Screening
Cervical cancer screening is recommended for many adults with a cervix between ages 21 and 65, although the specific test and interval depend on age and screening method.
Screening may involve:
- Cervical cytology, commonly called a Pap test
- High-risk HPV testing
- A combination of HPV testing and cervical cytology
Some people may require a different schedule because of previous abnormal results, immune-system conditions, prior cervical disease, or other factors.

7. Lung Cancer Screening
Lung cancer screening is not recommended for every adult.
The U.S. Preventive Services Task Force recommends annual screening with low-dose CT for adults aged 50 to 80 who:
- Have at least a 20 pack-year smoking history, and
- Currently smoke or quit within the past 15 years
A “pack-year” is based on the number of packs smoked per day multiplied by the number of years a person smoked.
For example, smoking one pack per day for 20 years equals 20 pack-years.
Your healthcare provider can help determine whether you meet the criteria for lung cancer screening.
8. Osteoporosis Screening
Osteoporosis weakens bones and increases the risk of fractures.
The U.S. Preventive Services Task Force recommends osteoporosis screening for women aged 65 and older.
Screening is also recommended for postmenopausal women younger than 65 who have increased fracture risk based on clinical risk assessment.
Bone-density testing is commonly performed using a DXA scan.
Your provider may consider factors such as:
- Age
- Body weight
- Previous fractures
- Family history
- Smoking
- Alcohol intake
- Certain medications
- Medical conditions affecting bone health
9. Depression and Mental Health Screening
Preventive healthcare is not limited to physical health.
The U.S. Preventive Services Task Force recommends screening adults for depression when appropriate systems are available for diagnosis, treatment, and follow-up.
Your healthcare provider may ask questions about:
- Mood
- Interest in usual activities
- Sleep
- Energy
- Concentration
- Stress
- Anxiety
You do not need to wait for a screening questionnaire to discuss concerns about your emotional wellbeing.
10. Sexually Transmitted Infection Screening
STI screening recommendations depend on factors such as age, pregnancy status, sexual history, number of partners, and individual risk.
Screening may include tests for conditions such as:
- HIV
- Chlamydia
- Gonorrhea
- Syphilis
- Hepatitis B or C in appropriate patients
Discussing sexual health honestly with your healthcare provider helps ensure that testing is based on your actual risk rather than assumptions.
Do You Need Every Screening Every Year?
No.
This is one of the most common misunderstandings about preventive care.
Some screenings may be recommended annually for eligible patients, while others may be performed every few years or only once under certain circumstances.
For example:
- Blood pressure may be checked frequently
- Some cancer screenings occur every few years
- Colorectal screening intervals depend on the test used
- Some patients need additional monitoring because of previous abnormal results
More testing is not automatically better. Appropriate screening is about choosing the right test for the right patient at the right time.
What If a Screening Result Is Abnormal?
An abnormal screening result does not always mean you have a disease.
Screening tests are designed to identify people who may need additional evaluation.
Your provider may recommend:
- Repeating the test
- Additional blood work
- Diagnostic imaging
- A more specific diagnostic test
- Monitoring over time
- Referral to a specialist
Follow-up is an important part of the screening process.
What Should You Tell Your Provider Before Screening?
Make sure your provider knows about:
- Your current medications
- Previous abnormal screening results
- Your family medical history
- Past surgeries
- Smoking history
- Pregnancy or pregnancy possibility
- New or persistent symptoms
- Major changes in weight or health
This information can affect which screenings are appropriate and how results are interpreted.
Screening Is Not the Same as Diagnosing Symptoms
Preventive screening is generally intended for people who do not have symptoms of the condition being screened for.
If you develop a concerning symptom, do not wait until your next screening appointment.
For example, persistent fatigue, leg swelling, blurred vision, or other unexplained changes may require a separate medical evaluation.

Frequently Asked Questions
What health screenings should every adult have?
There is no single screening list that applies to every adult. Blood pressure screening is widely recommended, while other tests depend on age, sex, health history, and individual risk.
Do I need blood work every year?
Not necessarily. The need for laboratory testing depends on your age, previous results, medications, medical conditions, symptoms, and risk factors.
At what age should cancer screening begin?
It depends on the type of cancer and your personal risk. For average-risk adults, colorectal cancer screening generally begins at 45, while current USPSTF breast cancer guidance recommends mammography beginning at 40. Other screenings use different criteria.
Can my primary care provider arrange preventive screenings?
Yes. Primary care providers commonly review preventive-care needs, order appropriate tests, and coordinate referrals for screenings such as mammography, colonoscopy, or other specialist services.
Should I get screened if I feel healthy?
Yes, when a screening is recommended for you. Preventive screening is specifically designed to identify certain conditions or risks before symptoms develop.
