Cancer screening explained

Screening means checking for early signs of a disease in people who do not have symptoms. For some cancers, screening programmes can help find changes early, when they are often easier to treat.

Why screening matters

Finding some cancers early, before symptoms appear, can make a real difference to outcomes. That is the idea behind national screening programmes for certain cancers.

How to know what is right for you

  • Screening recommendations depend on your age, sex, family history and other factors.
  • Which programmes are offered, and at what ages, varies by country.
  • Your doctor or national health service is the right source for what you should do and when.
Do not start or skip any screening based on a website. Speak with your doctor or follow your country's official screening programme.

Common questions

At what age should I be screened?

It depends on the cancer, your personal risk factors and your country's programme. Ask your doctor or check your national health service's official guidance.
