What is cancer screening?

Screening for cancer means looking for cancer before there are symptoms. Scientists have studied environments, lifestyles and patterns of cancer in the population to learn which people are more likely to get certain types of cancer. This information helps doctors identify people who should be screened for certain types of cancer, what type and how often screening should be done. Screening for some cancers is important because it can help the doctor discover cancer early and treat it successfully.

Screening is when a test is used to look for a disease before there are any symptoms. Cancer screening tests, including those for colorectal cancer, are effective when they can detect disease early. Detecting disease early can lead to more effective treatment.
