A good preventive medicine plan is the quietest, most valuable thing your doctor can do for you. It catches disease early, keeps vaccines current, and tracks the numbers — blood pressure, cholesterol, blood sugar, weight — that predict how the next decade will go. At MedexClinic, our family-medicine team builds a personalized preventive care calendar for every adult patient, so nothing important falls through the cracks.

This guide walks through what adult preventive medicine looks like decade by decade: which cancer screenings to schedule, which labs to repeat, which vaccines to update, and what Medicare and most commercial insurance plans typically cover.

Most of the conditions that shorten adult lives — cardiovascular disease, type 2 diabetes, several common cancers, osteoporosis — are either preventable or far more treatable when found early. The catch is that early disease rarely feels like anything. You feel fine right up until the day you don't.

A written preventive schedule solves that problem. Instead of waiting for symptoms, your primary care doctor orders the right screening at the right age, repeats it on the right interval, and compares it to your personal and family history. Under the Affordable Care Act, most commercial plans cover a long list of these screenings at no cost-sharing when ordered by an in-network provider, and Medicare covers an Annual Wellness Visit plus a specific menu of screenings for adults 65+.

Every adult preventive visit at our practice typically includes:

• A full history update — new diagnoses, medications, family history, lifestyle, mood, sleep
• Vital signs and BMI, with a blood-pressure check at every visit
• Review of recommended cancer screenings for your age and risk profile
• Lab work when due: lipid panel, fasting glucose or A1C, kidney and liver function, thyroid when indicated
• Immunization review — flu, COVID-19, Tdap, shingles, pneumococcal, HPV, hepatitis B, RSV when eligible
• Counseling on nutrition, physical activity, tobacco, sleep, and mental health
• A written plan with the next screening dates on your chart

Our clinical director, Dr. Asim Nouman, MD, is an experienced family physician with 18+ years of clinical practice, and he builds this visit around what's actually relevant to you — not a one-size-fits-all checklist.

This decade is about establishing baselines and getting ahead of the big ones. Even healthy adults should see a primary care doctor at least every one to three years.

Screenings and labs:

• Blood pressure at every visit; at least every two years if normal
• Cholesterol (lipid panel) starting by age 20, repeated every 4–6 years if normal risk
• Diabetes screening if overweight, with a family history, or during pregnancy
• Cervical cancer screening starting at 21 (Pap every 3 years, or co-testing with HPV every 5 years from 30)
• STI screening per CDC guidelines, including HIV at least once
• Skin exam if you have risk factors or a strong family history
• Depression and anxiety screening

Vaccines: annual flu, COVID-19 as recommended, Tdap booster every 10 years, HPV catch-up series through age 26 (and up to 45 in shared decision-making), hepatitis B if not previously vaccinated, meningococcal if indicated.

Your 40s are when screening really earns its keep. Cardiovascular risk starts to climb, and several major cancer screenings begin.

• Colorectal cancer screening starts at age 45 for average-risk adults — either a colonoscopy (every 10 years) or a stool-based test on a shorter interval
• Breast cancer screening with mammography is recommended starting at 40, every 1–2 years
• Cervical cancer screening continues (Pap + HPV co-testing every 5 years)
• Diabetes screening every 3 years starting at 35, or sooner with risk factors
• Lipid panel and cardiovascular risk calculation every 4–6 years, more often if abnormal
• Hepatitis C screening at least once in adulthood
• Eye exam every 2 years, and a baseline skin check

This is also the decade to talk candidly about weight, sleep apnea, and metabolic health. A physician-supervised plan — which may include nutrition, activity changes, and in some cases a GLP-1 medication as one part of a broader program discussed at consultation — can meaningfully change your trajectory.

Screening intensifies in this decade, and two new vaccines come online.

• Lung cancer screening with low-dose CT is recommended annually for adults 50–80 with a significant smoking history
• Colorectal cancer screening continues on your chosen interval
• Breast and cervical cancer screening continue; cervical screening can typically stop after 65 if prior results have been consistently normal
• Bone density (DEXA) scan for women at 65, or earlier with risk factors
• Abdominal aortic aneurysm one-time ultrasound for men 65–75 who have ever smoked
• Prostate cancer screening with PSA as a shared decision starting at 50 (earlier for higher-risk groups)
• Hearing and vision checks annually

Vaccines to add: shingles (zoster) vaccine at 50, pneumococcal vaccines starting at 65 (or earlier with certain conditions), and RSV vaccine for eligible adults.

Medicare covers a Welcome to Medicare visit in your first 12 months of Part B and an Annual Wellness Visit every year after. These aren't full physicals, but they are the backbone of senior preventive care: a health risk assessment, cognitive screening, fall-risk review, depression screening, and a personalized prevention plan.

Focus areas in this decade include:

• Fall prevention — balance, strength, home-safety review, medication review
• Cognitive screening and memory assessment
• Continued cancer screening per guidelines and life expectancy
• Bone density monitoring and osteoporosis treatment when indicated
• Diabetes and cardiovascular risk management
• Immunizations — annual flu (higher-dose for 65+), COVID-19, pneumococcal, shingles, RSV, Tdap

Most commercial plans under the Affordable Care Act cover preventive services graded A or B by the U.S. Preventive Services Task Force at no out-of-pocket cost when you see an in-network provider. That generally includes blood pressure checks, cholesterol and diabetes screening, cancer screenings on the recommended schedule, HIV and hepatitis screening, routine immunizations, and well-woman visits.

Medicare Part B covers the Welcome to Medicare visit, Annual Wellness Visits, cardiovascular and diabetes screening, mammography, colorectal and lung cancer screening for eligible adults, bone density scans, and routine immunizations. Our front-desk team is happy to verify your specific benefits before your visit — call (904) 444-2903.

The simplest first step is to book an adult physical or Annual Wellness Visit with a primary care doctor who will actually look at your full history and build a written schedule you can follow. Bring any outside records, a list of medications, and your family history going back two generations if you can.

At MedexClinic, we see patients at two Jacksonville locations — 9551 Baymeadows Rd, Suite 6, and 1395 Cassat Ave, Suite 3 — and we handle both the preventive visit and the follow-through on anything we find.
