Screening for Breast, Cervical, Colorectal (Colon), and Lung Cancers
The CDC supports screening for breast, cervical, colorectal (colon), and lung cancers.
The Pap test can find abnormal cells in the cervix which may turn into cancer. Pap tests also can find cervical cancer early, when the chance of being cured is very high. For more information, visit Cervical Cancer: What Should I Know About Screening?
CDC’s National Breast and Cervical Cancer Early Detection Program offers free or low-cost mammograms and Pap tests nationwide. Find out if you qualify.
Colorectal (Colon) Cancer
Colorectal cancer almost always develops from precancerous polyps (abnormal growths) in the colon or rectum. Screening tests can find precancerous polyps, so they can be removed before they turn into cancer. Screening tests also can find colorectal cancer early, when treatment works best.

Screening for ovarian, prostate, and skin cancers has not been shown to reduce deaths from those cancers.
The U.S. Preventive Services Task Force recommends against prostate specific antigen (PSA)-based screening for men who have no symptoms.

The U.S. Preventive Services Task Force has concluded that there is not enough evidence to recommend for or against routine screening (total-body examination by a clinician) to find skin cancers early. This recommendation is for people who do not have a history of skin cancer and who do not have any suspicious moles or other spots.
