Men's Health Screening: What Tests to Get at 30, 40, and 50

Men use preventive healthcare at lower rates than women across nearly every measure. They are less likely to have a primary care physician, less likely to attend annual checkups, and more likely to delay care when symptoms arise. The consequence is conditions detected later, when they are harder to treat. A systematic approach to screening, knowing what tests to request and when, reduces this gap without requiring significant time or expense.

The following is based on guidelines from the US Preventive Services Task Force (USPSTF), the American Heart Association, the American Cancer Society, and the Endocrine Society, synthesized for men at different age thresholds.

At Age 30: Establishing a Baseline

The 30s are when many chronic diseases begin their silent progression. Most men in this decade feel well, which makes establishing a baseline particularly useful for comparison in later years.

Blood pressure: One of the most important and most commonly skipped measurements. Hypertension is largely asymptomatic until it causes cardiovascular events. Optimal blood pressure is below 120/80 mmHg; values above 130/80 meet the American Heart Association’s threshold for hypertension. If normal, recheck every 1-2 years.

Fasting lipid panel (cholesterol): First measurement at 35 for average-risk men per USPSTF, or earlier if risk factors are present (family history, smoking, hypertension, diabetes, obesity). Total cholesterol, LDL, HDL, triglycerides, and increasingly non-HDL cholesterol are the key values.

Fasting glucose and hemoglobin A1c: Screening for prediabetes and type 2 diabetes. The American Diabetes Association recommends screening beginning at 35, or earlier for overweight adults (BMI above 25) with additional risk factors. Prediabetes affects approximately 96 million American adults, many undiagnosed.

Testosterone (if symptomatic): Not a routine screening test, but appropriate if symptoms of hypogonadism, low energy, reduced libido, difficulty building muscle, mood changes, are present. Low testosterone in men under 35 warrants investigation for underlying causes as discussed in Low Testosterone in Young Men: Causes, Diagnosis, and What Differs From Older Men.

BMI and waist circumference: Simple measurements with meaningful predictive value. Waist circumference above 40 inches in men is associated with increased metabolic risk beyond what BMI captures.

STI screening: Sexually active men with new or multiple partners should be tested for HIV (at least once, more frequently with ongoing risk), syphilis, gonorrhea, and chlamydia. These are consistently underdiagnosed in men.

Testicular self-examination: Testicular cancer most commonly occurs in men aged 15-35. Monthly self-examination allows early detection. It is the most curable cancer when caught early.

At Age 40: Cardiovascular and Metabolic Priority

The 40s are when cardiovascular risk begins compounding and when lifestyle-driven conditions become more evident on testing.

Repeat all 30s tests: Blood pressure, lipid panel, and glucose should be rechecked if not done recently. Frequency depends on prior results.

Diabetes screening (if not already done): By 45, the USPSTF recommends diabetes screening for all adults with BMI above 25. Earlier screening for men with family history, sedentary lifestyle, or obesity.

Cardiovascular risk calculation: A 10-year cardiovascular risk estimate (using the Pooled Cohort Equations or a similar validated calculator) incorporates age, sex, lipids, blood pressure, and smoking status to estimate heart attack and stroke risk. This calculation guides decisions about statin therapy and aspirin use.

Testosterone (if symptomatic): Age-related testosterone decline begins around age 30 and accelerates. By the early to mid-40s, low testosterone symptoms become more common. Two morning testosterone tests are the starting point if symptoms are present.

Colon cancer screening: The USPSTF now recommends beginning colorectal cancer screening at age 45 (previously 50). Options include colonoscopy every 10 years, stool-based tests (FIT test) annually, or stool DNA tests every 1-3 years.

Skin check: Melanoma incidence increases with age and UV exposure history. Annual full-skin examination by a dermatologist is appropriate for men with significant sun exposure history, many moles, or a family history of melanoma.

At Age 50: Adding Prostate and Cancer Screening

The 50s introduce prostate cancer screening as a decision point and raise the importance of addressing any elevated cardiovascular risk identified at 40.

PSA discussion: The USPSTF recommends that men 55-69 make an individualized decision about PSA screening after discussing the benefits and harms with their physician. Men at higher risk (African American men, those with a first-degree relative diagnosed with prostate cancer before 65) should have this discussion earlier, at 40-45. The nuance of PSA interpretation is covered in PSA Testing: Who Needs It and What the Numbers Mean.

Repeat lipid and cardiovascular risk assessment: If statin therapy was not started in the 40s and risk has evolved, this is a critical time to reassess.

Abdominal aortic aneurysm (AAA) screening: One-time ultrasound screening for men aged 65-75 who have ever smoked (100 or more cigarettes in their lifetime). If you are approaching 65 with a smoking history, this is the guideline.

Vision and hearing: Often overlooked in men’s health screening discussions, both decline significantly in the 50s. Baseline evaluation establishes where correction may be needed.

Bone density (if risk factors): Men at high risk of osteoporosis, those on long-term glucocorticoids, with low testosterone, with inflammatory bowel disease, or with hyperparathyroidism, should discuss bone density testing with their physician. The general recommendation for bone density screening in men without risk factors is age 70.
