If the country that you live in has an organized screening programme for a cancer, you will be invited to participate in screening for that cancer after you reach the recommended age. You should therefore wait to receive an invitation, but keep in mind that signs or symptoms of cancer may appear at any time, even if you recently had a screening test or if you are not at the recommended age for screening. If you notice anything unusual about your health that you think might be due to cancer, consult your doctor without delay and do not wait for an invitation to participate in screening.
If there is no organized screening programme for the three recommended types of cancer screening in your country, you could contact your national, regional, or local health authorities to find out why this is the case.
