Conditions library
Men's health, explained.
Cancers and the other conditions men face, each with the same clear layout: what it is, how common it is, the signs worth reporting, how it's found and treated, what you can do — and where it happens in the 3D body.
Showing guides that apply to the female body: the general guides, written with men in mind. Female-specific guides are listed below as coming soon.
Cancers
Cancer guides are always free. Start with the basics if the words are new.
Understanding cancer: the basics
What cancer is, how screening differs from diagnosis, what 'stage' means, and the main types of treatment — in plain English.
Cancer MenProstate cancer
Apart from skin cancer, the most common cancer in American men. Many grow slowly; some don't. Here's what it is, who is at risk, and how the PSA decision works.
Cancer EveryoneColorectal cancer
Cancer of the colon or rectum. Screening from age 45 can find it early — or prevent it by removing polyps before they turn into cancer.
Cancer EveryoneLung cancer
By far the leading cause of cancer death in the US. Smoking causes most of it — and a yearly low-dose CT scan can find it early in people at high risk.
Cancer MenTesticular cancer
A cancer of younger men — the average age at diagnosis is about 33. It's uncommon and usually very treatable. Know what's normal for you.
Cancer EveryoneBladder cancer
Much more common in men than women. Blood in the urine — even once, even painless — is the sign never to ignore.
Cancer EveryoneKidney cancer
Often found by chance on a scan done for something else. Smoking, extra weight and high blood pressure raise the risk.
Cancer EveryoneSkin cancer and melanoma
After 50, melanoma is more common in men than women. Learn the ABCDE signs and check your skin — including your back.
Cancer EveryoneMouth and throat cancer (including HPV-related)
More than twice as common in men. Tobacco and alcohol are classic causes; HPV now drives many throat cancers — and the HPV vaccine can prevent infection.
Cancer EveryoneLiver cancer
Most liver cancer grows in a liver already damaged by hepatitis, alcohol or fatty liver disease — and roughly two-thirds of cases are in men.
Cancer EveryonePancreatic cancer
Hard to find early because symptoms often appear only after it has spread. Smoking, diabetes and family history raise the risk.
Cancer MenBreast cancer in men
Rare, but real: men have breast tissue too. A lump under the nipple is the most common sign.
By body system
Heart and blood vessels
Abdominal aortic aneurysm (AAA)
A bulge in the body's main artery that usually causes no symptoms. Men 65–75 who have ever smoked should have a one-time ultrasound.
Heart EveryoneHeart disease and heart attack
The leading cause of death for men in the US. Most of it comes from narrowed coronary arteries — and much of it can be prevented.
Heart EveryoneHigh blood pressure
Half of US men have it, and most people feel nothing. A simple check finds it; habits and medicines control it.
Prostate, kidneys and bladder
Brain and mental health
Sexual and reproductive health
Digestion and liver
Metabolism and hormones
Low testosterone (hypogonadism)
Testosterone falls only slowly with age. Real hypogonadism needs symptoms plus two low morning blood tests — and treatment isn't right for everyone.
Metabolism EveryoneType 2 diabetes and prediabetes
Blood sugar that stays too high. Millions have it without knowing — and prediabetes can often be stopped from progressing.
Bones, joints and muscles
By life stage
