Screening for cancer means looking for cancer before there are symptoms. Scientists have studied patterns of cancer in the population to learn which people are more likely to get certain types of cancer. They have also studied environments and lifestyles that may contribute to the development of cancer. This information helps doctors identify
- People who should be screened for certain types of cancer
- What types of screening tests these people should have
- How often these tests should be done
For some cancer, screening is important because it can help doctors discover cancer early and treat it successfully. Treatment is likely to be more effective when cancer is detected early. Not all screening tests are helpful for all people, and some have risks. For this reason, the National Cancer Institute is studying many screening tests to find out how useful they are.
