    Lung Cancer Screening (PDQ®): Screening - Patient Information [NCI] - What is screening?

    Screening is looking for cancer before a person has any symptoms. This can help find cancer at an early stage. When abnormal tissue or cancer is found early, it may be easier to treat. By the time symptoms appear, cancer may have begun to spread.

    Scientists are trying to better understand which people are more likely to get certain types of cancer. They also study the things we do and the things around us to see if they cause cancer. This information helps doctors recommend who should be screened for cancer, which screening tests should be used, and how often the tests should be done.

    Bronchial adenoma is a rare type of cancer that starts in the mucous glands and ducts of the lung airways (bronchi) or windpipe (trachea), and in the salivary glands. Although the word "adenoma" means a noncancerous tumor, most bronchial adenomas are cancer and can spread to other parts of the body. Yet they often grow slowly and are treatable, so if you have one, keep in mind that they have a good outlook.

    It is important to remember that your doctor does not necessarily think you have cancer if he or she suggests a screening test. Screening tests are given when you have no cancer symptoms.

    If a screening test result is abnormal, you may need to have more tests done to find out if you have cancer. These are called diagnostic tests.
