Preventive Screenings, Explained in Plain Language

Quick Answer (TL;DR)

Screening looks for problems before symptoms appear, in people who feel well. Which tests apply depends mostly on your age, sex and family history.

What It Means

Common adult screening includes blood pressure, cholesterol, diabetes risk, cervical, breast and bowel cancer programmes, and in some countries abdominal aortic aneurysm and lung screening for smokers.

Why It Matters for Your Health

Screening works best when it is timely and appropriate. Done too often, or on the wrong people, it produces false alarms and unnecessary procedures rather than benefit.

Recommended Biomarker or Metric to Track

Keep a dated list of screenings completed and when the next is due.

Questions to Ask Your Doctor

Targeted questions based on latest clinical consensus statements.

1Which screenings am I due for, given my age and history?
2Does my family history change the timing?
3What are the realistic benefits and downsides of each?
4What happens if a result is abnormal?
5How will I be reminded next time?
