Common Screening Tests and When to Start Them

Screening tests find disease before symptoms appear. Learn the common screenings for colon, breast, lung and heart health, and when guidelines suggest starting.

A screening test looks for disease in people who feel well. Finding a condition early often means treatment works better and there are more options. Which screenings you need depends on your age, family history and other risks.

Colon cancer screening

Colonoscopy and other colorectal tests look for colon cancer and polyps, which can be removed before they become cancer. Current guidelines recommend starting at age 45 for average-risk adults. Earlier screening may be recommended for people with a family history or other risks.

Breast cancer screening

Mammography finds breast cancer, often before a lump can be felt. Current guidelines recommend screening every two years for women aged 40 to 74. Talk with your provider about your own risk and what you prefer.

Lung cancer screening

Low-dose CT scans are recommended for some adults who have a significant smoking history and currently smoke or quit recently. The screening is short and uses a low dose of radiation. Your provider can tell you whether you qualify.

Heart health

A coronary calcium score uses a CT scan to measure calcium in the heart arteries, which can indicate plaque. It is not routine for everyone. Your provider will decide whether it adds useful information based on your risk factors. See our post on heart disease risk for more.

Genetic testing

Genetic testing looks for changes in genes that may raise your risk of certain conditions. It is most useful when there is a strong family history. A provider can help you decide whether testing makes sense.
