A free, evidence-based guide to the 38 preventive check-ups that matter most for adults.
Vetted by GPs and specialists across cardiology, oncology, gynecology, urology and preventive medicine.
The check-ups with the strongest evidence come first – not a long, generic list.
See exactly what's due for you now, and what becomes relevant each decade.
38 preventive check-ups across six categories. For each: what to do, why, how often, and how to act on the result.
Blood work, teeth, skin, eyes, ears, sex-specific health.
VO2max, body composition, strength and balance.
Colonoscopy, arteries, heart imaging, breast and lung cancer.
Standard, boosters, age-triggered, seasonal, travel.
Blood pressure, skin, mental and brain health.
Genetic risk, glucose monitoring, biological age.
Most serious conditions – cardiovascular disease, cancer, diabetes, kidney failure – develop silently over years. By the time symptoms appear, the damage is often advanced and hard to reverse. Preventive check-ups catch them early, while they're still manageable or even reversible.

Every test can catch a problem early, but false alarms lead to more scans, biopsies and worry. This guide focuses on the checks with a real net benefit for your situation, and shows the trade-offs where they matter.
