Cancer screening is the use of methods such as blood tests, urine tests, DNA tests and medical imaging to look for cancer in people who have no symptoms, so that any cancer found can be treated earlier and more successfully. It plays a role in both preventing cancer and diagnosing it early, and its approaches fall into universal screening, offered population wide to a given age or sex group, and selective screening, aimed at people with elevated risk factors such as family history or smoking.
