From the twenties and thirties, the foundations are blood pressure checks, weight or BMI, and lifestyle review, with cholesterol and diabetes screening based on risk factors and family history. Testicular self-awareness is useful for younger men, given testicular cancer peaks in this age range.
From around 40 to 50, cardiovascular risk assessment becomes more important, including cholesterol and blood sugar. Discussions about PSA testing for prostate cancer generally begin around 50 for average-risk men, or earlier (40 to 45) for those with a family history or of Black ethnicity. Bowel (colorectal) cancer screening typically starts around 45 to 50 depending on your country's programme. Eye and other checks may be added with age.
Exact ages and programmes vary across the US, UK, Canada, and EU, so use your local screening guidance. The best step is a check-in with a doctor to build a screening plan matched to your age, family history, and risk factors, rather than relying on a fixed list.
