The big picture
Cardiovascular disease is the leading killer of men, and its main drivers — blood pressure, cholesterol, blood sugar, smoking, weight — are silent for decades and cheap to detect. The highest-value thing most men can do for their health is boring: know these numbers and act on them early. See our guides to blood pressure and diabetes.
Screenings by decade
- 20s–30s: blood pressure at least yearly; cholesterol baseline; diabetes screening if overweight with risk factors; skin checks; mental health check-ins — suicide risk in men is real and undertreated.
- 40s: everything above, plus cholesterol and glucose regularly; discuss heart-risk calculators with your doctor; colon cancer screening starts at 45 (colonoscopy or stool-based tests — the best test is the one you'll do).
- 50s–60s: prostate cancer discussion (below); continue colon screening; lung cancer CT screening if you have a significant smoking history; abdominal aortic aneurysm ultrasound once for men 65–75 who ever smoked.
Prostate screening: an honest take
PSA screening is a genuine judgment call, which is why guidelines say men 55–69 should make an individual decision with their doctor. The case for: it can catch aggressive cancer early. The case for caution: many prostate cancers grow so slowly they'd never cause harm, and treating them can cause incontinence and ED. Modern practice softens the dilemma — many low-risk cancers are now safely monitored (active surveillance) rather than treated. Higher-risk men (family history, Black men) should start the conversation earlier, around 40–45.
ED and testosterone: what's real
Erectile dysfunction is often an early warning of blood-vessel disease — the arteries involved are smaller than the heart's, so they show trouble first. New persistent ED deserves a real medical visit (blood pressure, glucose, lipids), not just an online pill. The medications (sildenafil, tadalafil) are effective, now inexpensive as generics — and dangerous combined with nitrates, so honesty about your medication list matters. Buying them from unverified websites is a leading source of counterfeits; verify any pharmacy first.
Testosterone: true deficiency is a real medical condition diagnosed with morning blood tests plus symptoms, and treatment genuinely helps those men. But fatigue and low mood alone are usually not testosterone problems — sleep apnea, depression, and metabolic issues are more common culprits. Be wary of clinics that sell testosterone to nearly everyone who walks in: therapy can suppress fertility and requires monitoring.
The unglamorous multipliers
- If you smoke, quitting is worth more than everything else on this page combined. Medications and quitlines (1-800-QUIT-NOW) double success rates.
- Alcohol — heavy drinking drives blood pressure, liver disease, and cancer risk; men are twice as likely to have alcohol problems.
- Sleep apnea — loud snoring plus daytime exhaustion, especially with a thick neck or high blood pressure, deserves a sleep study. Treatment changes lives.
- Mental health — men are less likely to be diagnosed with depression and far more likely to die by suicide. Irritability, anger, and drinking are common male presentations. Our mental health guide covers getting care; in crisis, call or text 988.
