Every year, around 695,000 Americans die from heart disease alone, making it the leading cause of death in the United States. Hundreds of thousands more receive late-stage cancer diagnoses that could have been detected much earlier. The most powerful tool we have to change those numbers is also one of the simplest: a regular preventive health screening.
The problem is that most people do not know which screenings they actually need, or when to start. Some assume it is too early. Others assume it is too late. Most have simply never been told.
One of the most common things we hear from patients at Altea Medical is that no one ever told them what to get checked for, or when. This guide is for those people.
Whether you are 28 or 68, this guide covers the preventive health screenings you need at every age, what each test is looking for, and why timing matters.

What is a preventive health screening?
A preventive health screening is a test or check carried out when you have no symptoms. The goal is to catch a problem early or confirm that everything looks normal. This is different from a diagnostic test, which is ordered after symptoms appear. Screenings are proactive. Diagnostics are reactive.
What the data shows
The guidelines for preventive health screenings are set and regularly updated by the U.S. Preventive Services Task Force (USPSTF), the CDC, and the American Heart Association. What you need depends on your age, sex, family history, and existing health conditions.
Preventive health screenings in your 20s and 30s
Many people in their 20s and 30s feel healthy and assume that means they do not need routine checks. But this is exactly the stage where establishing baselines matters most. Knowing your normal numbers makes it easier to spot changes later.
Blood Pressure
Check every 1 to 2 years if your readings are normal. High blood pressure has no symptoms, which is why it is often called the silent killer. According to the American Heart Association, nearly 1 in 2 American adults has high blood pressure, and many do not know it. A quick check at your annual visit is all it takes.
Cholesterol
A cholesterol baseline is worth having by your late 20s, especially with a family history of heart disease or stroke. High cholesterol has no symptoms, and catching it early gives you years to manage it through lifestyle changes before medication becomes necessary.
Blood sugar and diabetes risk
If you have risk factors such as excess weight, a sedentary lifestyle, or a family history of type 2 diabetes, a fasting blood glucose or HbA1c test can identify prediabetes early. Prediabetes is reversible. Type 2 diabetes is largely manageable when caught before complications develop.
Cervical cancer (Pap smear)
The USPSTF recommends a Pap smear every 3 years starting at age 21, or every 5 years combined with HPV testing from age 30. Cervical cancer is one of the most preventable cancers when screening starts on time.
STI screening, skin checks, and mental health
STI screening is recommended annually for sexually active adults under 25, or those with new or multiple partners. A full-body skin check is worth scheduling if you spend time outdoors or have a history of significant sunburn. Your annual visit is also the right time to discuss mental health, sleep, and lifestyle habits.
Preventive health screenings in your 40s and 50s
The 40s and 50s are when several important screenings either begin or become more frequent. Cardiovascular risk increases, and cancer screenings become a regular part of the picture.
Blood pressure and cholesterol
Blood pressure should now be checked annually. Cholesterol every 4 to 6 years if levels are normal, and more frequently if elevated. Your doctor may also run a cardiovascular risk assessment to calculate your 10-year risk of heart disease or stroke.
Diabetes screening
The USPSTF (U.S. Preventive Services Task Force) recommends screening for prediabetes and type 2 diabetes in adults aged 35 to 70 who are of a higher body weight. A fasting blood glucose or HbA1c test requires a single blood draw and can be done at your annual visit.
Breast cancer (mammogram)
For women at average risk, mammogram screening is recommended starting at age 40. Frequency depends on personal risk factors and should be discussed with your doctor. Those with a family history of breast cancer may be advised to start earlier.
Colorectal cancer screening
Updated USPSTF guidelines recommend starting colorectal cancer screening at age 45 for average-risk adults. Options include colonoscopy every 10 years, an annual stool-based test, or a CT colonography every 5 years. Talk to your provider about which is right for you.
Lung cancer screening
For adults aged 50 to 80 with a significant smoking history (20 pack-years or more) who currently smoke or quit within the past 15 years, the USPSTF recommends annual low-dose CT lung screening. This is one of the most impactful screenings for early detection in high-risk patients.
Preventive health screenings from 60 and beyond
From 60 onwards, all the screenings above continue, and several new ones are added. This is the stage where a more comprehensive checklist pays off.
Bone density (DEXA scan)
Women should have a bone density scan at age 65, earlier with risk factors such as smoking, low body weight, or a family history of osteoporosis. Men with risk factors may also benefit from earlier screening. A DEXA scan is quick, painless, and can prevent a first fracture from becoming a life-changing event.
Vision and hearing
Annual vision checks and periodic hearing assessments become important in your 60s. Uncorrected vision or hearing loss is linked to falls, cognitive decline, and reduced quality of life. Both are highly treatable when caught early.
Cognitive health screening
A brief cognitive assessment is part of the Medicare Annual Wellness Visit. Early signs of memory change are worth discussing with your doctor, particularly if there is a family history of dementia.
Shingles vaccine review and fall risk assessment
Adults aged 50 and over are recommended to receive the shingles vaccine (Shingrix) if they have not done so already. A fall risk assessment is also appropriate at this stage, reviewing medications, balance, home hazards, and footwear.
Preventive health screenings specific to men
From 60 onwards, all the screenings above continue, and several new ones are added. This is the stage where a more comprehensive checklist pays off.
Prostate cancer (PSA test)
Prostate cancer screening involves a shared decision-making conversation with your doctor rather than a blanket recommendation. For men at average risk, that conversation typically begins at 50. For men with a family history of prostate cancer, or who are Black, the conversation should happen at 45. The PSA test measures prostate-specific antigen levels in the blood.
Abdominal aortic aneurysm (AAA)
Men aged 65 to 75 who have ever smoked (100 or more cigarettes in their lifetime) are recommended to have a one-time abdominal ultrasound to screen for an abdominal aortic aneurysm. This painless, non-invasive scan can prevent a life-threatening emergency.
Preventive health screenings specific to women
In addition to the screenings covered above, women have several checks that are either exclusive to them or particularly important at certain life stages.
Pap smear and HPV testing
From age 21, a Pap smear every 3 years. From age 30, a Pap smear plus HPV co-test every 5 years. Screening can stop at age 65 if you have had adequate recent testing and no history of serious abnormalities.
Mammogram
Starting at 40 for average-risk women. Frequency and duration are based on individual risk profile. Women with a first-degree relative with breast cancer should discuss earlier and more frequent screening with their provider.
Bone density
DEXA scan from age 65, or earlier with risk factors such as early menopause, smoking, low body weight, or prolonged steroid use.
Well-woman visit
Even when you feel completely healthy. The well-woman visit is an annual opportunity to check all current screenings, update your health history, discuss hormonal changes, and keep your preventive care on track.
How family history can change your timeline
The standard guidelines for preventive health screenings by age are designed for people at average risk. If you have a family history of cancer, heart disease, or diabetes, your timeline may look different.
A family history of colon cancer before age 60 in a first-degree relative means starting colonoscopy screening 10 years earlier than standard. A strong family history of breast or ovarian cancer may warrant genetic testing and earlier mammography. A parent or sibling with type 2 diabetes increases your own risk significantly, pointing to earlier and more frequent blood sugar checks.
This is why your full family history matters at every visit. Not as a box to tick, but as real clinical information that shapes your care. If you are not sure what your family history includes, it is worth having that conversation with your relatives before your next appointment.
When should you talk to your doctor about screenings?
If any of the following apply to you, it is worth booking a visit to go over what you are due for:
- You have not had a primary care visit in over a year
- A family member has recently been diagnosed with heart disease, cancer, or diabetes
- You have reached a new decade and want to know what changes for your age group
- You have high blood pressure or elevated cholesterol and want to know what else to monitor
- You are newly pregnant or planning a pregnancy
- You are a smoker or former smoker who has never discussed lung or AAA screening
- You have never gone through your full family health history with a provider
